Sanjay Patel e0696ef613 Specify triple so 'make check' passes on darwin x86-64 
The check lines were added with:
http://reviews.llvm.org/rL256458
http://reviews.llvm.org/rL256460

but on a darwin target, the output looks like:
  ## InlineAsm Start
  rorq  %rdi
  ## InlineAsm End
  ## InlineAsm Start
  rorq  %rsi
  ## InlineAsm End
  leaq  (%rsi,%rdi), %rax
  retq

Evan Cheng 09f5be8146 Turn a 2-address instruction into a 3-address one when it's profitable even if the two-address operand is killed. 
e.g.
%reg1024<def> = MOV r1
%reg1025<def> = ADD %reg1024, %reg1026
r0            = MOV %reg1025

If it's not possible / profitable to commute ADD, then turning ADD into a LEA saves a copy.

Evan Cheng 968c3b0d6e Model inline asm constraint which ties an input to an output register as machine operand TIED_TO constraint. This eliminated the need to pre-allocate registers for these. This also allows register allocator can eliminate the unneeded copies.
