Let's make sure we aren't introducing new validation failures as
development proceeds. Basically, we record the current set of known
validation failures from the CTS, and for any validation failure we have
the layer log it and abort.
I had started encoding xfails from piglit, but it turns out that piglit
and the validation layer fight about the teardown process, producing
use-after-frees.

Otherwise, the access chain you emitted last time may not dominate the
current use.
Fixes the following validation failure in
dEQP-GLES31.functional.shaders.sample_variables.sample_mask_in.bits_unique_per_sample.multisample_texture_2:
UNASSIGNED-CoreValidation-Shader-InconsistentSpirv(ERROR / SPEC):

DXIL has no concept of subgroup mask ops, relative
shuffle ops, and everything is scalar.
Most wave broadcast ops support i1 overloads, except
for quad swap operations. Go figure. Use lower_bit_size
to promote those to i32 instead.

the code here was all expecting the VkPipelineStageFlags bitfield expansions,
but u_foreach_bit() gives the actual bit, so implicit feedback loops were never
actually being detected
instead, convert back to the bitfield at the top of the loop so the value works
as expected

Sometimes you want to diff 2 runs with INTEL_DEBUG=bat, but a tiny
allocation change can mess quite badly with offsets printed in the
decoding, making it hard to look at the diff with meld.
Fortunately our decoder can avoid printing offsets. We just need a
variable to specify that.
We still use the defaults specified by the driver but you can turn
things on/off with :
INTEL_DECODE=+color,-offsets,-floats INTEL_DEBUG=bat ./my_app

I stumbled on this when I inserted some suboptimal lowering code after all
optimizations. Adding certain subset of optimizations after my lowering code
actually avoided this bug, so I think it's not possible to hit this on upstream.
Let's fix this for the next person generating suboptimal code...
