Initial checkin of X86 backend. We can instruction select exactly one instruction 'ret void'. Wow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4284 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4707 91177308-0d34-0410-b5e6-96231b3b80d8
