abfd208cb0 nir: fix inserting the break instruction for partial loop unrolling
If the break in the original loop isn't in the first top-level if,
this would have re-inserted it in the wrong block.

Fixes this by re-inserting the break block to the corresponding break
block in the new loop by using the remap hashtable.

4a627af0e3 nir: don't take the derivative of the array index in nir_lower_tex
Previosuly when lowering to txd for sampler array the index would be
derived as well, therefore the resulting derivative would have been a
vec with one more component than what the txd instruction expects.

This patch truncates the coordinate vector in this case to make sure the
index is not derived.

0b3b4da82a nir: Handle array-deref-of-vec in var split passes
The changes are pretty straightforward.  For vector splitting, we just
ignore those vectors for now.  We could potentially handle array derefs
with a constant index (and probably should) but that's left for later.
For now, I'm mostly concerned with correctness of the pass.

15ab4d397f nir: Handle wildcards with casts in copy_prop_vars
If we're propagating a copy from a cast where the copy copies an entire
array, we end up with something like &((S *)ssa_N)->f[*] in the source
where a wildcard has a cast in its parent chain.  If we then try to
propagate the read into a non-wildcard array load, we have to specialize
the wildcard.  This breaks because nir_build_deref_follower() doesn't
handle casts.  Since we know a priori that, because wildcards are only
generated by copy_deref on arrays, we cannot have a cast with a wildcard
parent so simply chasing the source deref to the first wildcard will
ensure that any casts in the deref are handled properly.

f164edfe71 vtn: Add spirv_library_to_nir_builder feature
This new entrypoint takes in a SPIR-V blob and generates a header containing
a static inline nir_builder-family function for each function in the SPIR-V
library. The generated function will look for the function in the shader and, if
not found, insert a new nir_function with the appropriate signature -- to be
linked with the library later. Then, it will call the function, with the
appropriate gymnastics to handle return values as necessary.

This makes it super convenient to wrap CL libraries for use in a NIR pass.

things like *scan[op](b) with *scan[op](b2b32(b)).  For scan ops, this
assumes that b2b1(op(b1b32(x), b2b32(y))) = op(x, y) for all of the ops
iand, ior, and ixor.  This is true on all the back-ends I'm aware of.

Somebody less tired than me would add a unit test for this. Offending snippet:

        32    %58 = @load_reg (%55) (base=0, legacy_fabs=0, legacy_fneg=0)
        32    %57 = @load_reg (%55) (base=0, legacy_fabs=0, legacy_fneg=0)
        32    %21 = iadd %57, %15 (0x1)
                    @store_reg (%21, %55) (base=0, wrmask=x, legacy_fsat=0)
        32    %56 = @load_reg (%55) (base=0, legacy_fabs=0, legacy_fneg=0)
        32    %22 = i2f32 %56
        32    %23 = load_const (0x41000000 = 8.000000)
        32    %24 = fdiv %22, %23 (8.000000)
        32    %90 = mov %24
                    @store_reg_indirect (%90, %78, %58) (base=0, wrmask=x, legacy_fsat=0)

dfcca13800 compiler/types: Remove warnings about potential fallthrough
None of those cases are expected to fallthrough, but should be unreachable.
Just break them so they get to the unreachable entry at the end.
