Models a double-ended queue of elements from an a list. Based on NIR's worklist
data structure. This is useful in most backend compilers for data flow analysis.
Using this data structure has several advantages for backends:
* Simplicity, avoids open-coding a worklist data structure.
* Performance, the data structure is lighter weight than e.g sets
* Correctness, e.g. sets are nondeterministic and can cause random bugs.
Using a worklist approach at all is good for performance of liveness analysis
to avoid performing excess walks over the IR.

util_cpu_detect is an anti-pattern: it relies on callers high up in the call
chain initializing a local implementation detail. As a real example, I added:
...a Mali compiler unit test
...that called bi_imm_f16() to construct an FP16 immediate
...that calls _mesa_float_to_half internally
...that calls util_get_cpu_caps internally, but only on x86_64!
...that relies on util_cpu_detect having been called before.
As a consequence, this unit test:
...crashes on x86_64 with USE_X86_64_ASM set
...passes on every other architecture
...works on my local arm64 workstation and on my test board
...failed CI which runs on x86_64
...needed to have a random util_cpu_detect() call sprinkled in.
This is a bad design decision. It pollutes the tree with magic, it causes
mysterious CI failures especially for non-x86_64 developers, and it is not
justified by a micro-optimization.
Instead, let's call util_cpu_detect directly from util_get_cpu_caps, avoiding
the footgun where it fails to be called. This cleans up Mesa's design,
simplifies the tree, and avoids a class of a (possibly platform-specific)
failures. To mitigate the added overhead, wrap it all in a (fast) atomic
load check and declare the whole thing as ATTRIBUTE_CONST so the
compiler will CSE calls to util_cpu_detect.

You're not supposed to include a '\n' in mesa_log*() messages because
android logging will log what you provide on its own line anyway, so each
mesa_log() should be the body of a log line. But also, getting everyone
to consistently not do that is hopeless because we're all so trained by
printf(). So, just detect an existing \n and don't add a new one.

On mips64, the compiler does not allow use of non-zero argument with
__builtin_frame_address(). However, the returned frame address is only
used when PIPE_ARCH_X86 is defined. The compile error can be avoided
by making #ifdef PIPE_ARCH_X86 cover the getting of frame address too.
The argument checking of __builtin_frame_address() has been present
as a debug assert in clang 8. In clang 10, there is a proper runtime
check for the argument. This is why the build has not failed before.

Because we have to maintain two different packages of Mesa, one
specific to RADV and another one for RadeonSI and such, it's a bit
annoying to have to synchronize the drirc entries. Currently, only our
Mesa package installs 00-mesa-defaults.conf which means we have to
backport the drirc RADV changes.
This splits 00-mesa-defaults.conf in two to move the drirc RADV entries
to src/amd/vulkan/00-radv-defaults.conf. Meson will install the file
only if RADV is built.
There is still a caveat for common drirc workarounds like for WSI but
they are rare enough and we could still duplicate them if needed.
