[Patch, moxie] Clean up prologue and epilogue

Subject: [Patch, moxie] Clean up prologue and epilogue

I'm committing this patch.  It cleans up the moxie prologue and epilogue
code by using the short "dec" instruction in place of a load immediate
followed by add/sub (when possible).  It also shaves an instruction off
of the epilogue by popping saved register values off of $r12 instead of
using $sp.
