translating, just for efficiency)

nkeynes [Sun, 14 Dec 2008 07:50:48 +0000] tree

Setup a 'proper' stackframe in translated blocks. This doesn't affect performance noticeably,
but does ensure that
a) The stack is aligned correctly on OS X with no extra effort, and
b) We can't mess up the stack and crash that way anymore.
Replace all PUSH/POP instructions (outside of prologue/epilogue) with ESP-rel moves to stack
local variables.
Finally merge ia32mac and ia32abi together, since they're pretty much the same now anyway (and
thereby simplifying maintenance a good deal)
