While analyzing cache loading performance, hashing the pipeline layout was
surprisingly consuming around 4% of time, sometimes close to the cost of
hashing shader modules.
Turns out we were hashing the pipeline layout on every pipeline creation.
Considering that pipeline layouts are usually deduplicated by the
application, this was amplifying the hashing cost by a big margin.
With Graphics Pipeline Library, we do need to rebuild the pipeline layout
by combining those from each library, but we can memoize the hash of the
descriptor set layout. The cost of re-hashing hashes is negligible since
each descriptor set layout can amount to 1–2KB in size.

Android CTS 13_r4 tests dEQP-VK.memory.allocation.random* fail
with VK_ERROR_OUT_OF_DEVICE_MEMORY on ADL boards with 32GB memory
as memory allocation requests from DEQP are much larger(~2.9GB+)
based on device heap size/8.
Increase the limit to unsigned 32bit max(~4GB) which helps to
fix the dEQP-VK.memory.allocation.random* tests.

v2: Clean up comments to reflect the code change (Ivan Briano)
Update the value of MAX_MEMORY_ALLOCATION_SIZE (Lionel Landwerlin)

It's currently used when LS store output to LDS.
The LS/HS bug fix seems does not affect this case.
But we'd better treat it as other fixed args.

We have corresponding global dirty bits for each of the per-stage dirty

If a resource is dirty but already tracked by the current batch, no need
to process it at draw time.
Note that the batch could change (ie. new fb state bound, etc) after the
check if we need resource dirty tracking, but in these cases all the
dirty-resource state is marked dirty.

This wasn't taking into account a change in corresponding bit in
writeable_bitmask, causing problem if an SSBO was first bound for
read, and then rebound for write, we wouldn't update the buffers
valid range. Instead just drop the premature optimization.

Previously when there was an & or | with two BitmaskEnums, the compiler
would try to cast the RHS and find a matching overload, but there were
many different casts (to the enum itself, to an integer, to a boolean,
etc.) each with a matching overload which meant that it couldn't pick
one and errored out due to an ambiguous overload. Fix this by
explicitly providing an overload that takes a BitmaskEnum on the RHS.
It has to also provide a BitmaskEnum output, so that subsequent
operators with the result on the LHS (e.g. when or'ing together three
BitmaskEnums without any parentheses tricks) also get the right
overload.

NIR loop unrolling is only working if the loop counter is a scalar.
So keep the loop counter separate and move the aL emulation and
the aL increment to a new register.
This allows loop unrolling with vec4 backends where unconditional
scalarizing of phi nodes is undesirable, like for example r300.

Instead of using a SALU instruction to add to the scalar
offset, rely on the buffer swizzling and use constant offset.
