When --section-headers is used, GNU objdump prints both LMA and VMA for sections.
llvm-objdump does not do that what makes it's output be slightly inconsistent.
Patch teaches llvm-objdump to print LMA/VMA for ELF file formats.
The behavior for other formats remains unchanged.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

llvm-objdump.cpp
getRelocationValueString is a dispatcher function that calls the
corresponding ELF/COFF/Wasm/MachO implementations
that currently live in the llvm-objdump.cpp file.
These implementations better be moved to ELFDump.cpp,
COFFDump.cpp and other corresponding files, to move platform specific
implementation out from the common logic.
The patch does that. Also, I had to move ToolSectionFilter helper
and SectionFilterIterator, SectionFilter to a header to make them
available across the objdump code.

This is a cosmetic cleanup for the llvm-objdump code.
This patch:
* Renames things to match the official LLVM code style (lower case -> upper case).
* Removes few obviously excessive variables.
* Moves a few lines closer to the place of use, reorders the code a bit to simplify it,
to avoid doing excessive returns and to avoid using 'else` after returns.
I focused only on a llvm-objdump.h/llvm-objdump.cpp files. Few changes in the
MachODump.cpp and COFFDump.cpp are a result of llvm-objdump.h modification.

Summary:
With Mach-O, there is a flag requirement discrepancy between working with
universal binaries and thin binaries. Many flags that don't require the `-macho`
flag (for example `-private-headers` and `-disassemble`) fail to work on
universal binaries unless `-macho` is given. When this happens, the error
message is unhelpful, stating:
The file was not recognized as a valid object file.
Which can lead to confusion.
This change allows generic flags to be used on universal binaries with and
without the `-macho` flag. This means flags that can be used for thin files can
be used consistently with fat files too.
To do this, the universal binary support within `ParseInputMachO()` is extracted
into a new function. This new function is called directly from `DumpInput()`
when the input binary is universal. Additionally the `-arch` flag validation in
`ParseInputMachO()` was extracted to be reused.

and test cases for each of the error checks.
To do this more plumbing was needed so that the segment indexes and
segment offsets can be checked. Basically what was done was the SegInfo
from llvm-objdump’s MachODump.cpp was moved into libObject for Mach-O
objects as BindRebaseSegInfo and it is only created when an iterator for
bind or rebase entries are created.
This commit really only adds the error checking and test cases for the
bind table entires and the checking for the lazy bind and weak bind entries
are still to be fully done as well as the rebase entires. Though some of
the plumbing for those are added with this commit. Those other error
checks and test cases will be added in follow on commits.
Note, the two llvm_unreachable() calls should now actually be unreachable
with the error checks in place and would take a logic bug in the error
checking code to be reached if the segment indexes and segment
offsets are used from a checked bind entry. Comments have been added
to the methods that require the arguments to have been checked
prior to calling.

report_fatal_error().
No real functional change with this commit.
The problem with report_fatal_error() is it does not include the tool name
and the file name the for which the error message was generated.
Uses of report_fatal_error() were change to report_error() or error()
to get a better error and to make the code smaller and cleaner.
Also changed things like error(errorToErrorCode(SOrErr.takeError())) to
use report_error() with a file name and the llvm::Error (as well as the
ArchitectureName if available) so the error message is printed.

This adds behaviour similar to binutils' objdump which can show symbols in an
import library. Differences from that stem around the fact that we do not
create section symbols nor the all import import descriptor symbol reference.
However, this does mean that the tool can serve as a possible replacement for
the existing tool.

MachOUniversalBinary
and its clients to use the new llvm::Error model for error handling.
Changed getAsArchive() from ErrorOr<...> to Expected<...> so now all
interfaces there use the new llvm::Error model for return values.
In the two places it had if (!Parent) this is actually a program error so changed
from returning errorCodeToError(object_error::parse_failed) to calling
report_fatal_error() with a message.
In getObjectForArch() added error messages to its two llvm::Error return values
instead of returning errorCodeToError(object_error::arch_not_found) with no
error message.
For the llvm-obdump, llvm-nm and llvm-size clients since the only binary files in
Mach-O Universal Binaries that are supported are Mach-O files or archives with
Mach-O objects, updated their logic to generate an error when a slice contains
something like an ELF binary instead of ignoring it. And added a test case for
that.
The last error stuff to be cleaned up for libObject’s MachOUniversalBinary is
the use of errorOrToExpected(Archive::create(ObjBuffer)) which needs
Archive::create() to be changed from ErrorOr<...> to Expected<...> first,
which I’ll work on next.

when the object is from a slice of a Mach-O Universal Binary use something like
"foo.o (for architecture i386)" as part of the error message when expected.
Also fixed places in these tools that were ignoring object file errors from
MachOUniversalBinary::getAsObjectFile() when the code moved on to see if
the slice was an archive.
To do this MachOUniversalBinary::getAsObjectFile() and
MachOUniversalBinary::getObjectForArch() were changed from returning
ErrorOr<...> to Expected<...> then that was threaded up to its users.
Converting these interfaces to Expected<> from ErrorOr<> does involve
touching a number of places. To contain the changes for now the use of
errorToErrorCode() is still used in two places yet to be fully converted.

when the object is in an archive to use something like libx.a(foo.o) as part of
the error message.
Also changed llvm-objdump and llvm-size to be like llvm-nm and ignore non-object
files in archives and not produce any error message.
To do this Archive::Child::getAsBinary() was changed from ErrorOr<...> to
Expected<...> then that was threaded up to its users.
Converting this interface to Expected<> from ErrorOr<> does involve
touching a number of places. To contain the changes for now the use of
errorToErrorCode() is still used in one place yet to be fully converted.
Again there some were bugs in the existing code that did not deal with the
old ErrorOr<> return values. So now with Expected<> since they must be
checked and the error handled, I added a TODO and a comments for those.

to produce a real error message
Produce the first specific error message for a malformed Mach-O file describing
the problem instead of the generic message for object_error::parse_failed of
"Invalid data was encountered while parsing the file”. Many more good error
messages will follow after this first one.
This is built on Lang Hames’ great work of adding the ’Error' class for
structured error handling and threading Error through MachOObjectFile
construction. And making createMachOObjectFile return Expected<...> .
So to to get the error to the llvm-obdump tool, I changed the stack of
these methods to also return Expected<...> :
object::ObjectFile::createObjectFile()
object::SymbolicFile::createSymbolicFile()
object::createBinary()
Then finally in ParseInputMachO() in MachODump.cpp the error can
be reported and the specific error message can be printed in llvm-objdump
and can be seen in the existing test case for the existing malformed binary
but with the updated error message.
Converting these interfaces to Expected<> from ErrorOr<> does involve
touching a number of places. To contain the changes for now use of
errorToErrorCode() and errorOrToExpected() are used where the callers
are yet to be converted.
Also there some were bugs in the existing code that did not deal with the
old ErrorOr<> return values. So now with Expected<> since they must be
checked and the error handled, I added a TODO and a comment:
“// TODO: Actually report errors helpfully” and a call something like
consumeError(ObjOrErr.takeError()) so the buggy code will not crash
since needed to deal with the Error.
Note there is one fix also needed to lld/COFF/InputFiles.cpp that goes along
with this that I will commit right after this. So expect lld not to built
after this commit and before the next one.

to only print the first private header.
Which for Mach-O files only prints the Mach header and not the subsequent load
commands. Which is used by scripts to match what the darwin otool(1) with the
-h flag does without the -l flag.
For non-Mach-O files it has the same functionality as -private-headers (with
the trailing ’s’).

LLVM MC has single methods which can handle the output of EH frame and DWARF CIE's and FDE's.
This code improves DWARFDebugFrame::parse to do the same for parsing.
This also allows llvm-objdump to support the --dwarf=frames option which objdump supports. This
option dumps the .eh_frame section using the new code in DWARFDebugFrame::parse.

Previously we kept going on partly corrupted input, which might result
in garbage being printed, or even worse, random crashes.
Rafael mentioned that this is the GNU behavior as well, but after some
discussion we both agreed it's probably better to emit a reasonable
error message and exit. As a side-effect of this commit, now we don't
rely on global state for error codes anymore. objdump was the last tool
in the toolchain which needed to be converted. Hopefully the old behavior
won't sneak into the tree again.

Now that clang modules/PCH are object containers this option is useful to
