700841617a Add support for modeling whether or not the processor has support for 
conditional moves as a subtarget feature.  This is the easy part of 
PR4841.

a09caa56d6 Fixed the asmstrings for 8-bit, 16-bit, and 32-bit ADD %rAX, imm instructions. 
Added a 64-bit ADD %RAX, imm32 instruction.
Added all 4 forms for AND %rAX, imm and CMP %rAX, imm.

9b35a09e7e - Add target lowering methods to get the preferred format for the FDE and LSDA 
encodings.
- Make some of the values emitted by the FDEs dependent upon the pointer
  size. This is in line with how GCC does things. And it has the benefit of
  working for Darwin in 64-bit mode now.

7168a7dc6d llvm-mc/X86: Implement single instruction encoding interface for MC. 
- Note, this is a gigantic hack, with the sole purpose of unblocking further
   work on the assembler (its also possible to test the mathcer more completely
   now).

 - Despite being a hack, its actually good enough to work over all of 403.gcc
   (although some encodings are probably incorrect). This is a testament to the 
   beauty of X86's MachineInstr, no doubt! ;)

cbbea0ffc7 Expand i8 selects into control flow instead of 16-bit conditional 
moves. This avoids the need to promote the operands (or implicitly
extend them, a partial register update condition), and can reduce
i8 register pressure. This substantially speeds up code such as
write_hex in lib/Support/raw_ostream.cpp.

subclass-coalesce.ll is too trivial and no longer tests what it was
originally intended to test.

af70e5c676 Don't use INSERT_SUBREG to model anyext operations on x86-64, as it 
leads to partial-register definitions. To help avoid redundant
zero-extensions, also teach the h-register matching patterns that
use movzbl to match anyext as well as zext.
