Removes the bool_to_float logic from the int_to_float pass, so that both

lower_int.

While we're here, make the computation of the new probe address use a

nir: Rematerialize compare instructions
On some architectures, Boolean values used to control conditional
branches or condtional selection must be propagated into a flag. This
generally means that a stored Boolean value must be compared with zero.
Rather than force the generation of extra compares with zero, re-emit
the original comparison instruction. This can save register pressure by
not needing to store the Boolean value.
There are several possible ares for future improvement to this pass:
1. Be more conservative. If both sources to the comparison instruction
are non-constants, it may be better for register pressure to emit the
extra compare. The current shader-db results on Intel GPUs (next
commit) lead me to believe that this is not currently a problem.
2. Be less conservative. Currently the pass requires that all users of
the comparison match the pattern. The idea is that after the pass is
complete, no instruction will use the resulting Boolean value. The only
uses will be of the flag value. It may be beneficial to relax this
requirement in some cases.
3. Be less conservative. Also try to rematerialize comparisons used for
discard_if intrinsics. After changing the way the Intel compiler
generates cod e for discard_if (see MR!935), I tried implementing this
already. The changes were pretty small. Instructions were helped in 19
shaders, but, overall, cycles were hurt. A commit "nir: Rematerialize
comparisons for nir_intrinsic_discard_if too" is on my fd.o cgit.
4. Copy the preceeding ALU instruction. If the comparison is a
comparison with zero, and it is the only user of a particular ALU
instruction (e.g., (a+b) != 0.0), it may be a further improvment to also
copy the preceeding ALU instruction. On Intel GPUs, this may enable
cmod propagation to make additional progress.
v2: Use much simpler method to get the prev_block for an if-statement.

radeonsi/nir: Remove hack for builtins
We now bounds check properly in the uniform loading fast path, so
there's no need to disable it by pretending there are other UBO bindings
in use. The way this looks at the variable name was causing problems
when two piglit shaders, one with a name that triggered the hack and one
that didn't, got hashed to the same thing after stripping out the names.

radeonsi/nir: Use correct location for uniform access bound
location is the API-level location, but driver_location is the actual
location the uniform gets passed to the driver. This apparently only
caused failures with builtins, where the location is 0 because it's
represented via the state tokens instead.

radeonsi/nir: Correctly handle double TCS/TES varyings
ac expands the store to 32-bit components for us, but we still have to
deal with storing up to 8 components, and when a varying is split across
two vec4 slots we have to calculate the address again for the second
slot, since they aren't adjacent in memory. I didn't do this on the ac
level because we should generate better indexing arithmetic for the lds
store, where slots are contiguous.
