c248903b2a IMPLICIT_DEF was not the beautiful elegant solution I thought it was going

dbd7372665 Emit pseudo instructions to indicate that some registers are live on entrance 
and exit of the function.  This fixes bug: Jello/2003-05-06-LivenessClobber.llx

f158da2f78 Implement code to keep the stack pointer aligned to an 8 byte boundary. 
This improves the performance of the power benchmark by a few percent.
This will be neccesary for SSE code, which requires 16 byte alignment of
the stack.
