Add support for adding section relocations in -r mode. Enhance the test
cases which validate the parsing of .o files to also round trip. They now
write out the .o file and then parse that, verifying all relocations survived
the round trip.

If, during the initial parse of a template, we perform aggregate initialization
and form an implicit value initialization for an array type, then when we come
to instantiate the template and redo the initialization step, we would try to
match the implicit value initialization up against an array *element*, not to
the complete array.
Remarkably, we've had this bug since ~the dawn of time, but only noticed it
recently.

relaxed in the big RuntimeDyldMachO cleanup of r213293.
No test case yet - this was found via inspection and there's no easy way to test
GOT alignment in RuntimeDyldChecker at the moment. I'm working on adding support
for this now, and hope to have a test case for this soon.

This fixes all of the hidden ivar test cases and any case where we try to find the full definition of an objective C class.
This also means hidden ivars show up again.

Vector true is -1, not 1, which means we need to use the relational unary
macro instead of the normal unary builtin one.

relational.h includes relational macros for defining functions which need to
return 1 for scalar true and -1 for vector true.
I believe that this is the only place that this behavior is required, so the
macro is placed at its lowest useful level (same directory as it is used in).
This also creates re-usable unary/binary declaration and floatn includes which
should simplify relational builtin declarations.
Mostly patterned off of include/math/[binary_decl|unary_decl|floatn].inc
but with required changes for relational functions.

_lldb is built as an extension module on Windows. Normally to load
an extension module named 'foo', Python would look for the file
'foo.pyd'. However, when a debug interpreter is used, Python will
look for the file 'foo_d.pyd'. This change checks the build
configuration and creates the correct symlink name based on the
build configuration.

This makes us emit dllexported in-class initialized static data members (which
are treated as definitions in MSVC), even when they're not referenced.
It also makes their special linkage reflected in the GVA linkage instead of
getting massaged in CodeGen.

Speculative fix for a -Wframe-larger-than warning from gcc. Clang will

Summary:
Before this patch, you could get lines in the output such as:
Note: including file: ../../dist/include/js/Tc:/path/to/foo.cpp(1,1) : error(clang): static_assert failed...
This patch ensures that the stdout output from showIncludes won't be garbled
in the terminal like this, and it also helps applications that use the output
to generate dependency information if they happen to capture both stdout and
stderr.
Test Plan:
Tested locally, it's hard to write an automated test for this as
the behavior depends on the buffering of the ostreams.

Earlier when the code was in InstCombine, we were calling the version of ComputeNumSignBits in InstCombine.h
that automatically added the DataLayout* before calling into ValueTracking.
When the code moved to InstSimplify, we are calling into ValueTracking directly without passing in the DataLayout*.
This patch rectifies the same by passing DataLayout in ComputeNumSignBits.

The previous implementation of RuntimeDyldMachO mixed logic for all targets
within a single class, creating problems for readability, maintainability, and
performance. To address these issues, this patch strips the RuntimeDyldMachO
class down to just target-independent functionality, and moves all
target-specific functionality into target-specific subclasses RuntimeDyldMachO.
The new class hierarchy is as follows:
class RuntimeDyldMachO
Implemented in RuntimeDyldMachO.{h,cpp}
Contains logic that is completely independent of the target. This consists
mostly of MachO helper utilities which the derived classes use to get their
work done.
template <typename Impl>
class RuntimeDyldMachOCRTPBase<Impl> : public RuntimeDyldMachO
Implemented in RuntimeDyldMachO.h
Contains generic MachO algorithms/data structures that defer to the Impl class
for target-specific behaviors.
RuntimeDyldMachOARM : public RuntimeDyldMachOCRTPBase<RuntimeDyldMachOARM>
RuntimeDyldMachOARM64 : public RuntimeDyldMachOCRTPBase<RuntimeDyldMachOARM64>
RuntimeDyldMachOI386 : public RuntimeDyldMachOCRTPBase<RuntimeDyldMachOI386>
RuntimeDyldMachOX86_64 : public RuntimeDyldMachOCRTPBase<RuntimeDyldMachOX86_64>
Implemented in their respective *.h files in lib/ExecutionEngine/RuntimeDyld/MachOTargets
Each of these contains the relocation logic specific to their target architecture.
