Use the driver flag -fno-signed-zeros instead.

This was recommended but not implemented in D6873:

which was checked in at r226915:

Scalar integers are commuted to move constants to the RHS for re-association - this ensures vectors do the same.

Before:
  let theObject = {someMethodName() {
    doTheThing();
    doTheOtherThing();
  },
                   someOtherMethodName() {
                     doSomething();
                     doSomethingElse();
                   }};

After:
  let theObject = {
    someMethodName() {
      doTheThing();
      doTheOtherThing();
    },
    someOtherMethodName() {
      doSomething();
      doSomethingElse();
    }
  };

Don't assume that all pointers are convertible to void pointer.
Instead correctly respect [conv.ptr]p2; only allow pointer types with an
object pointee type to be caught as pointer-to-void.

The `HexagonELFType` is declared in the HexagonLinkingContext.h.

In all other ELF related classes we use `ELFT` abbreviation.

Functions in the files are hard to read because of line wrapping.
Use shorter names for local variables so that the lines fit
within 80 columns.

[X86] Apply AddedComplexity consistently for similar patterns. This keeps them together in the DAGISel tables and reduces table size slightly.

These functions are "constructors" of the LinkingContexts. We already
have auxiliary classes and functions for ELFLinkingContext in the header.
They fall in the same category.

getRelocationHandler is a public interface to get an instance of
TargetRelocationHandler. We don't use any member function other than
applyRelocations to a returned instance. Returning a base class instance
suffices here. (If a return type is a derived class, it looks like we were
using derived classes features.)

canParse took three parameters -- file magic, filename extension and
memory buffer. All but YAMLReader ignored the second parameter.
This patch removes the parameter.

Because of the previous change (r234074), ELFObjectReader became just
an alias for ELFReader. We can replace all occurrences of ELFObjectReader
with ELFReader.

In this patch, I also replaced ELFDSOReader to remove the alias template.

[X86] Don't use GR64 register 'and with immediate' instructions if the immediate is zero in the upper 33-bits or upper 57-bits. Use GR32 instructions instead.

Previously the patterns didn't have high enough priority and we would only use the GR32 form if the only the upper 32 or 56 bits were zero.

Fixes PR23100.

llvm-svn: 234075

So that we can remove one template parameter from ELFReader.
ELF port is heavily templatized, and I want to reduce the usage
where possible.

Only MIPS defined the member function, but this feature is not actually
MIPS-specific. Also, the dependency to the MIPS-only member function
prevented us from merging <Arch>ELF{Object,DSO}Reader classes.

This patch moves the feature from MipsLinkingContext to LinkingContext.

Not all of them (there's still a fallback for this specific function
that omits the type parameter) but it's some I bothered to do now.

This add support for catching an exception such that an exception object
available to the catch handler will be initialized by the runtime.

llvm-svn: 234062

We don't need to represent UnwindHelp in IR.  Instead, we can use the
knowledge that we are emitting the parent function to decide if we
should create the UnwindHelp stack object.

llvm-svn: 234061

The two classes are the same other than a few exceptions.
This patch merges them using templates.
