The old vote_eq implementation supported only booleans, but now
we have to support arbitrary values, so use the read_first_invocation
intrinsic + ballot.
I took this as an opportunity to figure out how easy it was to do this
in nir instead of in the nir_to_llvm pass, and it actually turned out
pretty okay IMO. Only creating the pass is some extra code.

The SPIR-V extension wants us to be able to do an AllEqual on any vector
or scalar type. This has two implications:
1) We need to be able to handle vectors so we switch the vote_eq
intrinsics to be vectorized intrinsics.
2) We need to handle floats which have different behavior with respect
to +-0, NaN, etc. than the integer variant so we need two variants.

This allows us to generate, for example,
"exp param0 v0, off, off, off" if only the first channel is needed.
Not sure if this improves performance but it's worth trying.

Currently both users of this would overflow an array when the
input was a dual slot double as they expected the number of
components to be a max of 4.
Since we pass the type we can just let the functions handle
doubles in a way they choose.

Until llvm handles indirects better we will need to use these

This is just useless for two reasons:
1) flush_bits is not set accordingly, so nothing will be flushed
in BeginQuery().
2) we always flush caches in EndCommandBuffer(), so if a reset
is done in a previous command buffer we are safe.

radeonsi, i965 and anv all treat fdd{x,y} opcodes the same as
fdd{x,y}_coarse by default. The SPIR-V spec lets the implementation
decide how it should be handled and radv was previously going
for the higher quality option. Here we change the shared amd
code to match how nir_op_fdd{x,y} is expected to be handled
by the other NIR drivers.
