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

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.
