gallium: Disambiguate TGSI_OPCODE_IF.

TGSI_OPCODE_IF condition had two possible interpretations:

- src.x != 0.0f

  - Mesa statetracker when PIPE_SHADER_CAP_INTEGERS was false either for
    vertex and fragment shaders
  - gallivm/llvmpipe
  - postprocess
  - vl state tracker
  - vega state tracker
  - most old drivers
  - old internal state trackers
  - many graw examples

- src.x != 0U

  - Mesa statetracker when PIPE_SHADER_CAP_INTEGERS was true for both
    vertex and fragment shaders
  - tgsi_exec/softpipe
  - r600
  - radeonsi
  - nv50

And drivers that use draw module also were a mess (because Mesa would
emit float IFs, but draw module supports native integers so it would
interpret IF arg as integers...)

This sort of works if the source argument is limited to float +0.0f or
+1.0f, integer 0, but would fail if source is float -0.0f, or integer in
the float NaN range.  It could also fail if source is integer 1, and
hardware flushes denormalized numbers to zero.

But with this change there are now two opcodes, IF and UIF, with clear
meaning.

Drivers that do not support native integers do not need to worry about
UIF.  However, for backwards compatibility with old state trackers and
examples, it is advisable that native integer capable drivers also
support the float IF opcode.

I tried to implement this for r600 and radeonsi based on the surrounding
code.  I couldn't do this for nouveau, so I just shunted IF/UIF
together, which matches the current behavior.

i965/vs: Generalize data structures pointed to by vec4_generator.

This patch removes the following field from vec4_generator, since it
is not used:

- struct brw_vs_compile *c

And changes the following field:

- struct gl_vertex_program *vp => struct gl_program *prog

With these changes, vec4_generator no longer refers to any VS-specific
data structures.  This will pave the way for re-using it for geometry
shaders.
