The set of supported vector sizes in NIR has holes in it. For example, we
support vec5 and vec8, but not vec6 or vec7. However, this pass did not take
that into account, and would happily shrink a vec8 down to a vec7, causing NIR
validation to fail. Instead, the pass should round up to the next supported
vector size.
Fixes NIR validation fail in OpenCL's test_basic hiloeo subtest.

This will be used for vc4, where incorrectly exposing 3D textures accounts
for most of the GLES2 conformance failures it has. This leaves
EXT_texture3d exposed in the (already non-conformant) GL2.1 support it
exposes, which has always been a best-effort thing.

Since the result of the fdot must be non-negative, the fabs can be

For example, the proof for this pattern
(('bcsel', ('flt', 'a@32', 0), 'b@32', 'c@32'), ('fcsel_ge', a, c, b)),
would be
bcsel(a < 0, b, c)
bcsel(!(a < 0), c, b)
bcsel(a >= 0, c, b)
fcsel_ge(a, c, b)
However, !(a < 0) => (a >= 0) is well known to produce different
results if `a` is NaN.
Instead of that replacement, use this replacement:
bcsel(a < 0, b, c)
bcsel(-0 < -a, b, c)
bcsel(0 < -a, b, c)
fcsel_gt(-a, b, c)
This is NaN-safe and exact.

nir_to_dxil() uses those types to pick the right operation overload,
and atomic loads/stores are no different from their non-atomic
counterpart apart from the atomicity property, so it makes sense to
