59c46ee655 IMPLICIT_DEF was not the beautiful elegant solution I thought it was going 
to be.  In fact, it made stuff worse.  :(

and exit of the function.  This fixes bug: Jello/2003-05-06-LivenessClobber.llx

013ad21206 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.
