History

Chris Lattner 3cc838433a Improve the FP stackifier to decide all on its own whether

an instruction kills a register or not.  This is cheap and 
easy to do now that instructions record this on their flags,
and this eliminates the second pass of LiveVariables from the
x86 backend.  This speeds up a release llc by ~2.5%.
