Evan Cheng d4a5c05c97 Completed :lower16: / :upper16: support for movw / movt pairs on Darwin. 
- Fixed :upper16: fix up routine. It should be shifting down the top 16 bits first.
- Added support for Thumb2 :lower16: and :upper16: fix up.
- Added :upper16: and :lower16: relocation support to mach-o object writer.

Owen Anderson ec47597ecd As far as I can tell, unified syntax uses c0-c15 instead of cr0-cr15 for mcr and friends.

Evan Cheng 965b3c7323 Model :upper16: and :lower16: as ARM specific MCTargetExpr. This is a step 
in the right direction. It eliminated some hacks and will unblock codegen
work. But it's far from being done. It doesn't reject illegal expressions,
e.g. (FOO - :lower16:BAR). It also doesn't work in Thumb2 mode at all.

Bill Wendling e6ff05c59d Sort the register list based on the *actual* register numbers rather than the 
enum values we give to them. <rdar://problem/8823730>

Jason W Kim 9c5b65d289 1. Support ELF pcrel relocations for movw/movt: 
R_ARM_MOVT_PREL and R_ARM_MOVW_PREL_NC.
2. Fix minor bug in ARMAsmPrinter - treat bitfield flag as a bitfield, not an enum.
3. Add support for 3 new elf section types (no-ops)

Daniel Dunbar 9d944b3fcc McARM: Add more hard coded logic to SplitMnemonicAndCC to also split out the 
carry setting flag from the mnemonic.

Note that this currently involves me disabling a number of working cases in
arm_instructions.s, this is a hopefully short term evil which will be rapidly
fixed (and greatly surpassed), assuming my current approach flies.

Rafael Espindola 290d71671e Implement cfi_def_cfa. Also don't convert to dwarf reg numbers twice. Looks 
like 6 is a fixed point of that and so the previous tests were OK :-)

Daniel Dunbar 45140d2efc MC/Mach-O/ARM: We always use the SECTDIFF reloc type on ARM, which is

Rafael Espindola 844f6b6cfb Relax alignment fragments. 
With this we don't need the EffectiveSize field anymore. Without that field
LayoutFragment only updates offsets and we don't need to invalidate the
current fragment when it is relaxed (only the ones following it).

This is also a very small improvement in the accuracy of the layout info as
we now use the after relaxation size immediately.
