255eafbd49 Simplify the byte reordering logic slightly.

d8e351b96f VLDR fixups need special handling under Thumb. While the encoding is the same, 
the order of the bytes in the data stream is flipped around.

52e635ea35 A bit of cleanup: early exit ApplyFixup and cache the Fixup offset. No 
functionality change.

179821ac1f Remove the instruction fragment to data fragment lowering since it was causing 
freed data to be read. I will open a bug to track it being reenabled.

Lifted adjustFixupValue() from Darwin for sharing w ELF.

TODO:
  refactor ELFObjectWriter::RecordRelocation more.
  Possibly share more code with Darwin?
  Lots more relocations...

36d76a8dbc MC/Mach-O: Switch to using MachOFormat.h. 
- I'm leaving MachO.h, because I believe it has external consumers, but I would really like to eliminate it (we have stylistic disagreements with one another).

679cbd3b21 Add support for a few simple fixups to the ARM Darwin asm backend. This allows 
constant pool references and global variable refernces to resolve properly
for object file generation. For example,

int x;
void foo(unsigned a, unsigned *p) {
  p[a] = x;
}

can now be successfully compiled directly to an (ARM mode) object file.

This also adds support for

mov zed+(bar-foo), %eax

d4d4f4f488 I added a new file ARMAsmBackend which stubs out in similar ways to 
the eqv X86 class.
For now, I split the ELFARMAsmBackend from the DarwinARMAsmBackend
(also mimicking X86)

Tested against -r115126
