Rafael Espindola 70d6e0e0ff Correctly produce R_X86_64_32 or R_X86_64_32S. 
With this patch in

movq    $foo, foo(%rip)
foo:
.long   foo

We produce a R_X86_64_32S for the first relocation and R_X86_64_32 for the
second one.

Jason W Kim 645f6c2bef Tiny patch for proof-of-concept cleanup of ARMAsmPrinter::EmitStartOfAsmFile() 
Small test for sanity check of resulting ARM .s file.

Jan Wen Voung b96b2d8e4d Have ELFAsmParser.cpp use the already parsed "Size" (entry size) when 
constructing a section. Test for a few cases also included.

Rafael Espindola 2ebaee9c75 Make it possible for the MCObjectWriter to decide if a given fixup is fully 
resolved or not. Different object files have different restrictions and
different native assemblers have different idiosyncrasies we want to emulate
for now.

Move the existing MachO logic to the new place and implement an ELF one that
gets fixups to globals right.

Jason W Kim b32124545b 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

Evan Cheng 2fb20b1d37 ARM instruction itinerary fixes: 
1. Cortex-a9 8-bit and 16-bit loads / stores AGU cycles are 1 cycle longer than 32-bit ones.
2. Cortex-a9 is out-of-order so model all read cycles as cycle 1.
3. Lots of other random fixes for A8 and A9.

Owen Anderson 99c985c37d Fix PR8247: JumpThreading can cause a block to become unreachable while still having predecessor, if it is part of a self-loop. 
Because of this, we cannot use the Simplify* APIs, as they can assert-fail on unreachable code.  Since it's not easy to determine
if a given threading will cause a block to become unreachable, simply defer simplifying simplification to later InstCombine and/or
DCE passes.

Jim Grosbach 0860520527 Add specializations of addrmode2 that allow differentiating those forms 
which require the use of the shifter-operand. This will be used to split
the ldr/str instructions such that those versions needing the shifter operand
can get a different scheduling itenerary, as in some cases, the use of the
shifter can cause different scheduling than the simpler forms.

Chris Lattner f60062fd55 add basic avx support to the disassembler, also teach it about ssmem/sdmem 
operands.

With this done, we can remove the _Int suffixes from the round instructions
without the disassembler blowing up.  This allows the assembler to support
them, implementing rdar://8456376 - llvm-mc rejects 'roundss'
