This should not be a change in behavior, as all current cases that
potentially answer "yes" require SSA.
The next patch will introduce another case that requires SSA.

Designated initializers with anonymous unions don't work in MSVC or
GCC < 4.6. With a couple of constructor methods, we don't need them any
more and the code is actually cleaner.

As it was, we weren't ever using load_const in a non-SSA way. This allows
us to substantially simplify the load_const instruction. If we ever need a
non-SSA constant load, we can do a load_const and an imov.

We stopped generating predicates in glsl_to_nir some time ago. Right now,
it's all dead untested code that I'm not convinced always worked in the
first place. If we decide we want them back, we can revert this patch.

nir_metadata_dirty was a terrible name because the parameter it takes is
the metadata to be preserved. This is really confusing because it looks
like it's doing the opposite of what it is actually doing. Now it's named
sensibly.

This commit renames nir_instr_as_texture to nir_instr_as_tex and renames
nir_instr_type_texture to nir_instr_type_tex to be consistent with
nir_tex_instr.

This pass is still fairly basic. It only handles ALU operations, constant
loads, and phi nodes. No texture ops or intrinsics yet.
