228180c2ae Print another class of instructions correctly, giving us: xorl EDX, EDX
for example.

42f51b24e1 Check not only for MO_VirtualRegister, but MO_MachineRegister as well when
printing out assembly. After all, we want the real thing too.

cd1f56fc36 Start trying to print instructions more correctly. For now we also print out the opcode for each instruction as well.

492e05ba01 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.

d25a097994 Initial checkin of X86 backend.
We can instruction select exactly one instruction 'ret void'.  Wow.
