Rather than having a ton of patterns for double shift instructions, e.g. SHLD16rrCL, just perform custom dag combine to form x86 specific dag so they match to the same pattern. This also makes sure later dag combine do not cause isel to miss them (e.g. promoting i16 to i32).

on darwin empty functions need to codegen into something of non-zero length,
...
otherwise labels get incorrectly merged. We handled this by emitting a
".byte 0", but this isn't correct on thumb/arm targets where the text segment
needs to be a multiple of 2/4 bytes. Handle this by emitting a noop. This
is more gross than it should be because arm/ppc are not fully mc'ized yet.

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.)
