Provide fd_rd_output facilities which enable constructing RD dumps that are
stored into gzip-compressed output. This matches the default behavior of
libwrap. Enabling and adjusting the behavior of functionality is done
through the FD_RD_DUMP environment variable.
Integration into Turnip's MSM backend is covered, replacing the previous
RD dump that was enabled through TU_DEBUG=rd. That debug option still
works and is the same as using FD_RD_DUMP=enable.
By default the dumps are created for each submission, using the provided
submit index. FD_RD_DUMP=combine enables gathering dumps for submissions
for the given logical device into a single file.
In the Turnip integration, FD_RD_DUMP=full will force dumping contents of
any buffer object. Additionally, with that option enabled any previous
submit will be waited on.
Specifying FD_RD_DUMP=trigger sets up a trigger file that can be used to
activate dumping manually. Writing zero or some non-integer value to the
file will disable dumping. Writing a positive integer value to it will
enable dumps for that many future submissions. Writing -1 to it will enable
dumps until disabled.

NIR caching is useful for two use cases:
- Shader permutations involving reused VS or FS.
- GPL-like engine that compiles a separate (library) variant and an
optimized (monolithic) variant, e.g. DXVK.
By caching the result of radv_shader_spirv_to_nir, permutations hitting
the cache can have their compilation time reduced by 50% or more.
There are still open questions about the memory and storage footprint of
NIR caches, which is why this is gated behind a perftest flag. In
particular, Steam doesn't want to ship NIR cache since they are
unnecessary in presence of a full precompiled shader cache. In this
commit, the cache entries do not reside in memory and are immediately
written to the disk. Further design around how the caches are stored and
how to coordinate cache type with Steam etc. is left as future work.

Demoting means that we don't execute any writes to memory but
otherwise the invocation continues to execute. Particularly,
subgroup operations and derivatives must work.
Our implementation of discard does exactly this by using
setmsf to prevent writes for the affected invocations, the
only difference for us is that with discard/terminate we
want to be more careful with emitting quad loads for tmu
operations, since the invocations are not supposed to be
running any more and load offsets may not be valid, but with
demote the invocations are not terminated and thus we should
emit memory reads for them to ensure quad operations and
derivatives from invocations that have not been demoted still
work.
Since we use the sample mask to implement demotes we can't tell
whether a particular helper invocation was originally such
(gl_HelperInvocation in GLSL) or was later demoted
(OpIsHelperInvocationEXT added with SPV_EXT_demote_to_helper_invocation),
so we use nir_lower_is_helper_invocation to take care of this.
