This currently treats coarse and fine derivatives the same, but Qualcomm
needs to know whether just coarse derivatives are used or fine
derivatives/quad ops are also used. Rename this to
needs_coarse_quad_helper_invocations make clear the difference from the
new field, needs_full_quad_helper_invocations.

This is needed for SPIR-V 1.6 support in OpenCL. This capability enables
the Uniform and UniformId decorations which prior were Shader only.
The CTS ends up using those decorations on function arguments, but we can
just ignore handling them there for now.
Fixes the spirv16_uniformdecoration_uniform and
spirv16_uniformdecoration_uniformid CL CTS test inside test_spirv_new.

Bifrost LDEXP.v2f16 takes a 16-bit exponent, which requires messy
lowering. The codegen for this is quite bad currently, but would be
improved by implementing unpack_32_2x16_split_*, and by fusing
comparisons with CSEL.
The main alternative is converting to F32, then LDEXP.f32, then
converting back to F16. This has better codegen for dynamic exponents
currently, but worse in the common case with a constant exponent where
all the saturating cast logic can be folded.

Right now the aliasing/overlapping checks are only done with index
0. I guess that was done because variables don't get a different
internal location even if you have a different index.
But doing that, the checks would not detect a case like this:
layout(location = 0, index = 1) out vec4 color;
layout(location = 0, index = 1) out vec4 factor;
That was used on the following piglit parser test:
spec/arb_explicit_attrib_location/1.10/compiler/layout-13.frag
And as the spec included on that test, is a link error case:
" * if more than one varying out variable is bound to the same
number and index; or"
This commit executes the aliasing checks for index 1 too, and moves
the skip down, to only skip if the current variable and all previous
location-assigned variables has different index and location.
The bad news is that now such assigned variables need to be tracked on
OpenGL-ES. Before that commit that was avoided.
With this commit the mentioned parser test properly fails to link in
any driver.
