There's really no need for two negation fields. This came from the
GL_NV_fragment_program extension. The new, unified Negate bitfield applies
after the absolute value step.

The i965 driver needs an extra instruction field for color output information.
It was using the Sampler field for this. Use the Aux field instead. This
will probaby be revisited at some point...

GLSL shadow() sampler calls are properly propogated down to the driver now.
The glean glsl1 shadow() tests work (except for the alpha channel).

Previously, "in-place" swizzles such as:
MOV t, t.xxyx;
were handled incorrectly. Fixed by splitting the one loop into two loops so we
get all the refs before assigning them (to avoid potential clobbering).

Mostly:
- update #includes
- update STATE_* token code

This driver comes from Tungsten Graphics, with a few further modifications by
Intel.
