Use shift/mask operations to access r_symbolnum rather than relying on
MachO::relocation_info. This should fix the big-endian bot failures that were
caused by 386f1c11.

Remove the llvm/Support/StringPool.h file and related support now that it has no clients.  A plain old StringSet<> is a better replacement.

Temporarily reverts commit d10386e1
because it breaks the Windows build. MSVC complains about an ambiguous
call to an overloaded function.

I've always found the "findValue" a little odd and
inconsistent with other things in SDB.

This simplfifies the code in SDB to just handle a splat constant
address or a 2 operand GEP in the same BB. This removes the
need for "findValue" since the operands to the GEP are
guaranteed to be available. The splat constant handling is
new, but was needed to avoid regressions due to constant
folding combining GEPs created in CGP.

CGP is now responsible for canonicalizing gather/scatters into
this form. The pattern I'm using for scalarizing, a scalar GEP
followed by a GEP with an all zeroes index, seems to be subject
to constant folding that the insertelement+shufflevector was not.

Summary:
This patch implements running linting on llvm-libc using build rule targets.

1) adds a new target per entrypoint for linting with the naming convention `<qualified_target_name>.__lint__` e.g `libc.src.string.strlen.__lint__`.
2) makes the build target for each entrypoint depend on the linting targets so that they run along with compilation of each entrypoint.
3) adds a lint all target named `lint-libc`.  `check-libc` now depends on this new target.
4) linting creates a lot of additional targets from clang and clang-tidy that need to be built so an opt out flag can be passed to cmake: `LLVM_LIBC_ENABLE_LINTING`.

Summary:
Do not reexport libgcc.a symbols and random sanitizer internal symbols
by applying a version script to the shared library build.

This fixes unwinder conflicts on Android that are created by reexporting
the unwinder interface from libgcc_real.a. The same is already done in
asan and hwasan.

[NFC] Introduce a `LateInitialize()` method to `SymbolizerTool` that is called during the LateInitialize stage of the sanitizer runtimes.

Summary:
This is implemented by adding a `Symbolizer::LateInitializeTools()`
method that iterates over the registered tools and calls the
`LateInitialize()` method on them.

`Symbolizer::LateInitializeTools()` is now called from the various
`Symbolizer::LateInitialize()` implementations.

The default implementation of `SymbolizerTool::LateInitialize()`
does nothing so this change should be NFC.

This change allows `SymbolizerTool` implementations to perform
any initialization that they need to perform at the
LateInitialize stage of a sanitizer runtime init.

[CallSite removal][IPO] Change implementation of AbstractCallSite to store a CallBase* instead of CallSite. NFCI.

CallSite will likely be removed soon, but AbstractCallSite serves a different purpose and won't be going away.

This patch switches it to internally store a CallBase* instead of a
CallSite. The only interface changes are the removal of the getCallSite
method and getCallBackUses now takes a CallBase&. These methods had only
a few callers that were easy enough to update without needing a
compatibility shim.

In the future once the other CallSites are gone, the CallSite.h
header should be renamed to AbstractCallSite.h

This removes the conditional layout of relocation_info bitfields that was
introduced in 3ccd677b (svn r358839). The platform relocation_info
struct (defined in usr/include/mach-o/reloc.h) does not define the layout of
this struct differently on big-endian platforms and we want to keep the LLVM
and platform definitions in sync.

To fix the bug that 3ccd677b addressed this patch modifies JITLink to construct
its relocation_info structs from the raw relocation words using shift and mask
operations.

llvm-addr2line: assume addresses on the command line are hexadecimal rather than attempting to guess the base based on the form of the number.

Summary:
This matches the behavior of GNU addr2line. We previously treated
hexadecimal addresses as binary if they started with 0b, otherwise as
octal if they started with 0, otherwise as decimal.

This only affects llvm-addr2line; the behavior of llvm-symbolize is
unaffected.

Pointed out by Adrian.

Converting a function pointer to an object pointer is illegal as nothing
requires it to be in the same address space. Add an overload for
function pointers so we don't convert do this illegal conversion, and
simply print out "function pointer".

The SIP debugserver was calling in attach_failed_due_to_sip
haven't worked for a while; remove them.  To check this
properly we'd need debugsever to call out to codesign(1) to
inspect the entitlements, or the equivalant API,
and I'm not interested in adding that at this point.  SIP
is has been the default on macOS for a couple of releases
and it's expected behavior now.

Following 38ca7b11

MLIR supports operations with resizable operand lists, but this property must
be indicated during the construction of such operations. It can be done
programmatically by calling a function on OperationState. Introduce an
ODS-internal trait `ResizableOperandList` to indicate such operations are use
it when generating the bodies of various `build` functions as well as the

These substitutions are strongly tied to the operation of the test
format, so it makes sense to have them defined by the test format
instead of the Lit configuration. They should be defined regardless
of which configuration is in use.

The recent change in the API macros revealed that we were not printing
the pointer address for a bunch of methods, but rather the address of
the pointer. It's something I had already noticed while looking at some
reproducer traces, but hadn't made it to the top of my list yet. This
fixes the issue by providing a more specific overload.

Fixes:
1. Setting the number of entries in a thread's clock to max between
   the thread and the SyncClock the thread is acquiring from
2. Setting last_acquire_
