Built OK for me on OSX and Linux (Ubuntu) with configure/make and CMake. Will
keep an eye on the bots....

Steward! Could you place this chair by the aft sun deck? I'm trying to get away
from the Astors. They are such boors!

Also added tests for ELF and COFF.

the immediate field of pshufw is actually an 8-bit field, not a 8-bit field that is sign extended.  This fixes PR8288

so and also change X86 for consistency.

Investigating if this can be improved a bit.

but not the "3dnowa" ones.

else in X86), and add support for pavgusb.  This is apparently the
only instruction (other than movsx) that is preventing ffmpeg from building
with clang.

If someone else is interested in banging out the rest of the 3DNow! 
instructions, it should be quite easy now.

1. Model dual issues as two FUs.
2. Model the pipelines correctly: two symmetric ALUs, the multiplier is a
   dependent pipeline on ALU0.
The changes do not have much impact on codegen right now. But I plan to make
pre-RA scheduler multi-issue aware which should take good advantage of the
changes.
