the flaky test set down to 4 tests, and dropping any remaining test

gmem or bypass didn't help, and adding lots of CCU flushing didn't help.

nir: Insert b2b1s around booleans in nir_lower_to

By inserting a b2b1 around the load_ubo, load_input, etc. intrinsics
generated by nir_lower_io, we can ensure that the intrinsic has the
correct destination bit size.  Not having the right size can mess up
passes which try to optimize access.  In particular, it was causing
brw_nir_analyze_ubo_ranges to ignore load_ubo of booleans which meant
that booleans uniforms weren't getting pushed as push constants.  I
don't think this is an actual functional bug anywhere hence no CC to
stable but it may improve perf somewhere.

nir: Add b2b opcodes

These exist to convert between different types of boolean values.  In
particular, we want to use these for uniform and shared memory
operations where we need to convert to a reasonably sized boolean but we
don't care what its format is so we don't want to make the back-end
insert an actual i2b/b2i.  In the case of uniforms, Mesa can tweak the
format of the uniform boolean to whatever the driver wants.  In the case
of shared, every value in a shared variable comes from the shader so
it's already in the right boolean format.

The new boolean conversion opcodes get replaced with mov in
lower_bool_to_int/float32 so the back-end will hopefully never see them.
However, while we're in the middle of optimizing our NIR, they let us
have sensible load_uniform/ubo intrinsics and also have the bit size
conversion.

These are I/O masks that are a subset of inputs_read and outputs_read
