2cf8c8cba4 nir/opt_copy_prop_vars: drop reuse of dynamic arrays
After the previous commit there are so few to reuse that this is no
longer worth doing and actually causes compilation to slow down.

The Blender shader compile time in issue #9326 improves as folows:
21.11 seconds -> 9.90 seconds

The CTS test dEQP-GLES31.functional.ubo.random.all_per_block_buffers.20

d56e739417 nir/opt_copy_prop_vars: skip cloning of copies arrays until needed
Most of the variables in the hash table will never actually be looked up
for any given block so cloning every possible value just creates a bunch
of unrequired memcpy calls.

Here we change the code to only clone the copies array once it is
actually looked up for the first time.

The Blender shader compile time in issue #9326 improves as folows:
151.09 seconds -> 21.11 seconds

The BITFIELD_MASK() macro is intended for using with actual bitfields,
not with nir_component_mask_t. This means we do some extra work to
handle values that are invalid for nir_component_mask_t in the first
place.

This eliminates some warnings on Clang, where the compiler complains
about casting UINT32_MAX to UINT16_MAX.

d9af5277b3 nir/copy_prop_vars: Handle volatile better
For deref_store, we can still delete invalid stores that write to
statically OOB data.  For everything, we need to make sure that we kill
aliases of destinations even if it's volatile.

d3737002ee nir/lower_atomics_to_ssbo: Also lower barriers
This is more correct for a pass which is supposed to completely lower
away atomic counters.  It also lets us stop supporting atomic counter
barriers in most of the drivers.

e40b11bbcb nir: Rename nir_intrinsic_barrier to control_barrier
This is a more explicit name now that we don't want it to be doing any
memory barrier stuff for us.

60097cc840 nir: Add a new memory_barrier_tcs_patch intrinsic
Right now, it's implemented as a no-op for everyone.  For most drivers,
it's a switch case in the NIR -> whatever which just breaks.  For ir3,
they already have code to delete tessellation barriers so we just add a
case to also delete memory_barrier_tcs_patch.
