instructions as the Mac OS X darwin assembler. Some of which like 'fcoml'
assembled to different opcodes. While some of the suffixes were just different.

Fixed the encoding of the x86 push instructions. Using a 32-bit immediate value
...
caused the a pushl instruction to be incorrectly encoding using only two bytes
of immediate, causing the following 2 instruction bytes to be part of the 32-bit
immediate value. Also fixed the one byte form of push to be used when the
immediate would fit in a signed extended byte. Lastly changed the names to not
include the 32 of PUSH32 since they actually push the size of the stack pointer.

on darwin empty functions need to codegen into something of non-zero length,

otherwise labels get incorrectly merged. We handled this by emitting a

needs to be a multiple of 2/4 bytes. Handle this by emitting a noop. This

Because of the EMMS problem, right now we have to support
...
user-defined operations that use MMX register types, but
the compiler shouldn't generate them on its own. This adds
a Synthesizable abstraction to represent this, and changes
the vector widening computation so it won't produce MMX types.
(The motivation is to remove noise from the ABI compatibility
part of the gcc test suite, which has some breakage right now.)
