Brian Gaeke e74543584a 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.
