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.

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.

This needs a test, but it will take some time to figure
out the best way to get an input that will produce > 2^16 relocs.

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.

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.

Add support for a missed case when the symbols in a difference
expression are in the same section but not the same fragment.

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.

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).

This CL delays reading of function bodies from initial parse until
materialization, allowing overlap of compilation with bitcode download.

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.

needed to emit a 64-bit gp-relative relocation entry. Make changes necessary
for emitting jump tables which have entries with directive .gpdword. This patch
does not implement the parts needed for direct object emission or JIT.

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.

This enables the linker to match concrete relocation types (absolute or relative) with whatever library or C++ support code is being linked against.

When not using subsections via symbols, the assembler can resolve
symbol differences (including pcrel references) to non-local
labels at assembly time, not just those in the same atom.
