Update MCSymbolizer and its subclasses' constructors to reflect the fact that
they take ownership of the RelocationInfo they're constructed with.

Move MCSymbolizer's constructor into header. It's trivial - there's no need for
it to be out-of-line.

Assert that MCSymbolizer is constructed with a valid (or at least non-null)
RelocationInfo argument.

Fix for pr18931: Crash using integrated assembler with immediate arithmetic

Fix description:
Expressions like 'cmp r0, #(l1 - l2) >> 3' could not be evaluated on asm parsing stage,
since it is impossible to resolve labels on this stage. In the end of stage we still have
expression (MCExpr).
Then, when we want to encode it, we expect it to be an immediate, but it still an expression.
Patch introduces a Fixup (MCFixup instance), that is processed after main encoding stage.

AVX-512: Implemented masking for integer arithmetic & logic instructions.

[cleanup] Modernize doxygen comments for the BumpPtrAllocator and
rewrite some of them to be more clear.

The terminology being used in our allocators is making me really sad. We
call things slab allocators that aren't at all slab allocators. It is
quite confusing.

[cleanup] Run clang-format over these routines to remove formatting
differences from subsequent diffs, and ease review. Going to be
performing some major surgery to simplify this stuff.

[mips] Stop caching the result of hasMips64(), isABI_O32(), isABI_N32(), and isABI_N64() from MipsSubTarget in MipsTargetLowering

Summary:
The short name is quite convenient so provide an accessor for them instead.

No functional change

[mips] Implement custom MCELFStreamer.

This allows us to insert some hooks before emitting data into an actual object file.
For example, we can capture the register usage for a translation unit by overriding
the EmitInstruction method. The register usage information is needed to generate
.reginfo and .Mips.options ELF sections.

[mips] NaCl should now use the custom MipsELFStreamer (recently added) in spite
of MCELFStreamer.

This is so that changes to MipsELFStreamer will automatically propagate through
its subclasses.

No functional changes (MipsELFStreamer has the same functionality of MCELFStreamer
at the moment).
