1761f49491 DebugInfo: When asm printing include a '[def]' tag for tag decls that are definitions (& rename the 'fwd' tag to 'decl' for clarity)

13fa254a61 [yaml2obj][ELF] Allow expressing undefined symbols.
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.

891dc92008 [yaml2obj][ELF] Don't explicitly set Binding with STB_*
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 ;)

This is another minor cleanup; to bring enum names in line

b71a2e2f2e Update the X86 disassembler to use xacquire and xrelease when appropriate.
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.

b36f148890 [yaml2obj][ELF] Add the section name -> section index map to State.
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.

8c70d558d3 [MC] Support @ variants with directional labels
The assembler parser common code supports recognizing symbol variants
using the @ modifer.  On PowerPC, it should also be possible to use

labels as well.

99f0423d50 [PowerPC] Optimize @ha/@l constructs
This patch adds support for having the assembler optimize fixups
to constructs like "symbol@ha" or "symbol@l" if "symbol" can be
resolved at assembler time.

This optimization is already present in the PPCMCExpr.cpp code
for handling PPC_HA16/PPC_LO16 target expressions.  However,
those target expression were used only on Darwin targets.

This patch changes target expression code so that they are
usable also with the GNU assembler (using the @ha / @l syntax
instead of the ha16() / lo16() syntax), and changes the
MCInst lowering code to generate those target expressions
where appropriate.

It also changes the asm parser to generate HA16/LO16 target
expressions when parsing assembler source that uses the
@ha / @l modifiers.  The effect is that now the above-
mentioned optimization automatically becomes available
for those situations too.

e143b13aca [PowerPC] Support compare mnemonics with implied CR0

assembler is supposed to support extended mnemonics for the compare
instructions where no condition register is specified explicitly
(and CR0 is assumed implicitly).

This patch adds support for those extended compare mnemonics.
