ed5af94373 nir: Transform discard_if(true) into discard
Noticed while reviewing Tim Arceri's NIR inlining series.

Without his series:

instructions in affected programs: 16 -> 14 (-12.50%)
helped: 2

With his series:

instructions in affected programs: 196 -> 174 (-11.22%)

1aa8a0392f nir: Optimize out discard_ifs with a constant 0 argument.
I found this in a shader that was doing an alpha test when alpha is fixed
at 1.0.

v2: Rebase on master (now the const value is "u32" not "u").

This matches the "foreach x in container" pattern found in many other
programming languages.  Generated by the following regular expression:

s/nir_foreach_function(\([^,]*\),\s*\([^,]*\))/nir_foreach_function(\2, \1)/

9076c4e289 nir: update opcode definitions for different bit sizes
Some opcodes need explicit bitsizes, and sometimes we need to use the
double version when constant folding.

v2: fix output type for u2f (Iago)

v3: do not change vecN opcodes to be float. The next commit will add
    infrastructure to enable 64-bit integer constant folding so this is isn't
    really necessary. Also, that created problems with source modifiers in
    some cases (Iago)

v4 (Jason):
  - do not change bcsel to work in terms of floats
  - leave ldexp generic

Squashed changes to handle different bit sizes when constant
folding since otherwise we would break the build.

v2:
- Use the bit-size information from the opcode information if defined (Iago)
- Use helpers to get type size and base type of nir_alu_type enum (Sam)
- Do not fallback to sized types to guess bit-size information. (Jason)

Squashed changes in i965 and gallium/nir drivers to support sized types.
These functions should only see sized types, but we can't make that change
until we make sure that nir uses the sized versions in all the relevant places.
A later commit will address this.

5ec456375e nir: Separate texture from sampler in nir_tex_instr
This commit adds the capability to NIR to support separate textures and
samplers.  As it currently stands, glsl_to_nir only sets the texture deref
and leaves the sampler deref alone as it did before and nir_lower_samplers
assumes this.  Backends can still assume that they are combined and only
look at only at the texture index.  Or, if they wish, they can assume that
they are separate because nir_lower_samplers, tgsi_to_nir, and prog_to_nir
all set both texture and sampler index whenever a sampler is required (the
two indices are the same in this case).

ee85014b90 nir/tex_instr: Rename sampler to texture
We're about to separate the two concepts.  When we do, the sampler will
become optional.  Doing a rename first makes the separation a bit more
safe because drivers that depend on GLSL or TGSI behaviour will be fine to
just use the texture index all the time.
