Add support for destination writemasks.
...
This involved changing dest operands to have their own structure like src
operands, as the destination writemask (which is align16-only) shares space
with register numbers in align1 mode.

Add support for predicate control.

This is untested on programs using predicate control, and also causes a
shift/reduce conflict.

Add support for swizzle control on source operands.
...
This required restructuring to store source operands in a new structure rather
than being stored in instructions, as swizzle is align16-only and shares
storage with other fields for align1 mode.
These changes were not tested on real programs using swizzle.

Lex the register number with the register name.

This avoids the need for a start condition to prevent for example g1.8<0,1,0>UW
