The current code base only supports the minimum set of tls-related
relocations and @modifiers that are necessary to support compiler-
generated code. This patch extends this to the full set defined
in the ABI (and supported by the GNU assembler) for the benefit
of the assembler parser.

This adds support for the @higher, @highera, @highest, and @highesta
modifers, including some missing relocation types.

This adds the relocation type and other necessary infrastructure
to use the @toc@h modifier in the assembler.

This adds necessary infrastructure to support the @h modifier.
Note that all required relocation types were already present
(and unused).
This patch provides support for using @h in the assembler;
it would also be possible to now use this feature in code
generated by the compiler, but this is not done yet.

This renames more VK_PPC_ enums, to make them more closely reflect
the @modifier string they represent. This also prepares for adding
a bunch of new VK_PPC_ enums in upcoming patches.
For consistency, some MO_ flags related to VK_PPC_ enums are
likewise renamed.
No change in behaviour.

The output can be in different orders, which breaks the test in some
situations. I have not yet found out what the root cause of the order
difference is. This fixes our internal build. If it is not the right
solution, feel free to roll back.

This is apart of a series of patches to encapsulate PtrState.RRI and
make PtrState.RRI a private field of PtrState.
*NOTE* This is actually the second commit in the patch stream. I should
have put this note on the first such commit r184528.

Previously we unconditionally enforced that section references in
symbols in the YAML had a name that was a section name present in the
object, and linked the references to that section. Now, permit empty
section names (already the default, if the `Section` key is not
provided) to indicate SHN_UNDEF.

Instead, just have 3 sub-lists, one for each of
{STB_LOCAL,STB_GLOBAL,STB_WEAK}.
This allows us to be a lot more explicit w.r.t. the symbol ordering in
the object file, because if we allowed explicitly setting the STB_*
`Binding` key for the symbol, then we might have ended up having to
shuffle STB_LOCAL symbols to the front of the list, which is likely to
cause confusion and potential for error.
Also, this new approach is simpler ;)

it at the moment.
This allows to form more paired loads even when stack coloring pass destroys the
memoryoperand's value.

This is another minor cleanup; to bring enum names in line
with the corresponding @modifier names, this renames:
VK_PPC_TOC -> VK_PPC_TOCBASE
VK_PPC_TOC_ENTRY -> VK_PPC_TOC16
No code change intended.

This is a bit tricky as the xacquire and xrelease hints use the same bytes,
0xf2 and 0xf3, as the repne and rep prefixes.
Fortunately llvm has different llvm MCInst Opcode enums for rep/xrelease
and repne/xacquire. So to make this work a boolean was added the
InternalInstruction struct as part of the Prefix state which is set with the
added logic in readPrefixes() when decoding an instruction to determine
if these prefix bytes are to be disassembled as xacquire or xrelease. Then
we let the matcher pick the normal prefix instructionID and we change the
Opcode after that when it is set into the MCInst being created.

This just re-sorts the big switch statement in
PPCELFObjectWriter::getRelocTypeInner to follow
the (numerical) order of the reloc types, and
fixes a couple of whitespace issues.

The custom lowering causes llc to crash with a segfault.
Ideally, the custom lowering can be fixed, but this allows
programs which load/store v2i32 to work without crashing.

After this patch, the ELF file produced by
`yaml2obj-elf-symbol-basic.yaml`, when linked and executed on x86_64
(under SysV ABI, obviously; I tested on Linux), produces a working
executable that goes into an infinite loop!

One of the key things that the YAML format abstracts over is the use of
section numbers for referencing sections. Instead, textual section names
are used, which yaml2obj then translates into appropriate section
numbers. (Technically ELF doesn't care about section names (only section
numbers), but since this is a testing tool, readability counts).
This simplifies using section names as symbolic references in various
parts of the code. An upcoming commit will use this to allow symbols to
reference sections.

MIPS does not handle multiple relocations correctly, so two tests from the
unittests are expected to fail. These are:
- MCJITTest.return_global and
- MCJITTest.multiple_functions.
Until the multiple relocations are fixed, XFAIL the MCJIT unittests for
MIPS. This issue is tracked as Bug 16250.
