5c14769849 Output UTF-8-encoded characters as identifier characters into assembly
by default.

This is a behaviour configurable in the MCAsmInfo. I've decided to turn
it on by default in (possibly optimistic) hopes that most assemblers are
reasonably sane. If this proves a problem, switching to default seems
reasonable.

I'm not sure if this is the opportune place to test, but it seemed good
to make sure it was tested somewhere.

f467eceb2a Fixed two leaks in the MC disassembler. The MC
disassembler requires a MCSubtargetInfo and a
MCInstrInfo to exist in order to initialize the
instruction printer and disassembler; however,
although the printer and disassembler keep
references to these objects they do not own them.
Previously, the MCSubtargetInfo and MCInstrInfo
objects were just leaked.

I have extended LLVMDisasmContext to own these
objects and delete them when it is destroyed.

e8ce31af5d Implement relocation-overflow behavior for PE/COFF.
This needs a test, but it will take some time to figure

646dff508a On ELF, create relocations to the abbreviation and line sections when producing
debug info for assembly files. We were already doing the right thing when
producing debug info for C/C++.

ELF linkers don't know dwarf, so they depend on these relocations to produce
valid dwarf output.

02bf78f5ca ARM BL/BLX instruction fixups should use relocations.
We on the linker to resolve calls to the appropriate BL/BLX instruction
to make interworking function correctly. It uses the symbol in the
relocation to do that, so we need to be careful about being too clever.

To enable this for ARM mode, split the BL/BLX fixup kind off from the
unconditional-branch fixups.

34c9c293e1 Switch the llvm::Triple class to immediately parse the triple string on
construction. Simplify its interface, implementation, and users
accordingly as there is no longer an 'uninitialized' state to check for.
Also, fixes a bug lurking in the interface as there was one method that
didn't correctly check for initialization.

6c7c6fe0c2 Don't lazily allocate eh_frame. We're not lazily allocating things like the LSDA, which are only used when the eh frame is used, so this lazy allocation doesn't really make sense.
Fix the type of eh_frame on Solaris so that Sun ld doesn't fail to combine them (thus making it impossible for the unwind library to find them and breaking exceptions).

122fc49297 Modified the Enhanced Disassembler to create and
cache disassemblers according to the string value
of the target triple, not according to the enum
of the triple CPU.  The reason for this is that
certain attributes of the instruction set are not
reflected in the enum, but only in the string.

for emitting jump tables which have entries with directive .gpdword. This patch
does not implement the parts needed for direct object emission or JIT.

cb876a7560 Fixed a crash in llvm-mc for Mach-O when a symbol difference expression uses a
symbol from an assignment.  In this case the symbol did not have a fragment so
MCObjectWriter::IsSymbolRefDifferenceFullyResolved() should not have been
calling IsSymbolRefDifferenceFullyResolvedImpl() with a NULL fragment and should
just have returned false in that case.
