35880f394f Instead of checking op.getType() against MO_VirtualRegister and 
MO_MachineRegister, we no longer distinguish Virtual vs. Machine registers
externally, they're ALL registers, all equal.

Registers are only differentiated whether they are >=
MRegisterInfo::FirstVirtual or not.

1617e6c997 SSARegMap -- the mapping between SSARegisters and their RegisterClasses, which 
imply types of SSA Registers. This is on a per-function basis, so the
MachineFunction contains the SSARegMap, and has accessor functions to it.

32f3d08cde Convert to use an enum to access def/use/use&def information. These make 
reading code much easier than just seeing "true, false" especially when
default parameters default one but not both arguments.

6559bb96a9 include/llvm/CodeGen/MachineInstrBuilder.h: Add addClobber() inline 
convenience method.  Fix typo in comment.
lib/Target/X86/InstSelectSimple.cpp: Explicitly specify some implicit uses.
 Use MOVZX/MOVSX instead of MOV instructions with sign extend instructions.
 Take out LEAVE instructions.
 32-bit IDIV and DIV use CDQ, not CWQ (CWQ is a typo).
 Fix typo in comment and remove some FIXME comments.
lib/Target/X86/Printer.cpp: Include X86InstrInfo.h and llvm/Function.h.
 Add some simple code to Printer::runOnFunction to iterate over
  MachineBasicBlocks and call X86InstrInfo::print().
lib/Target/X86/X86InstrInfo.def: Make some more instructions with
 implicit defs "Void".  Add more sign/zero extending "move" insns
 (movsx, movzx).
lib/Target/X86/X86RegisterInfo.def: Add EFLAGS as a register.

a2bae305fb Remove separate vector of implicit refs from MachineInstr, and 
instead record them as extra operands in the operands[] vector.
Also, move CallArgsDescriptor into this class instead of making it an
annotation on the machine instruction.

is now linear time instead of constant time, and thus is deprecated!
