b2e4972339 isaspec: Add BitSetEnumValue object
There might be cases where you describe an enum in isaspec and want it to use
for decoding but also for codegen with e.g. mako.

Lets have a look at the following exmaple:

<enum name="#cond">
	<value val="0" display=""/>    <!-- always: display nothing -->
	<value val="1" display=".gt"/>
	...
</enum>

In the decoding case we want that nothing gets displayed if #cond has the value of "0". For
codegen with mako this could result in the following C code:

enum PACKED cond {
   COND_ = 0,
   COND_GT = 1,
   ...
};

What you really want is this:

enum PACKED cond {
   COND_ALWAYS = 0,
   COND_GT = 1,
   ...
};

To make this possible introduce BitSetEnumValue class which represents
an isaspec xml enum. It holds the value, displayname and now a name.

With the  __str__ method the old behaviour is still intact.

b67cac5eba isaspec: Add support for custom meta information
Allows every user of isaspec to add custom meta information
to any bitset. This can be quite handy if you want to know
how many sources your instruction have, if this instruction has
a dest or provide some names for sources that can be used
by some debug tools.

All you need is to sprinkle <meta> tags in the xml file and
provide custom attributes.
  <meta has_dest="1" num_sources="3" .. />

With get_meta() method of any bitset you can get access to
the dict with all the attributes. get_meta() walks the whole
tree to collect all <meta> tags on the way to the root node.

038680c2f6 isaspec: Add initial decoding support
This reuses the <map> entries in the <encode> block to go in the reverse
direction and parse an instruction into a machine-readable structure. It
currently assumes that <map> entries are simple l-values like
"src->src[0]" or "src->flag", which is enough for afuc, but the plan for
the future is to use the <decode> block to allow us to override that for
more complex cases.

86b17d96b3 isaspec: Add "displayname" for altering {NAME} when decoding
In afuc, we have the situation where there are a number of ALU
instructions with two (almost) completely different encodings, including
a different opcode location, etc. These need to be different leaf
bitsets with different names for the encoder to work, because otherwise
the encoder has no way of descriminating between them, but when
displaying them we want to use the same name. This adds a small facility
to make the name used for {NAME} when displaying and for the opcode
when encoding different, so that e.g. OPC_ADDI can display as "add"
instead of "addi".

Because these are being included across subdir boundaries, the name
"decode" is potentially pretty overloaded.  Instead, prefix them with
"isaspec_".  Also, since they're both weird includes now and not really
complete files in their own right, give them a descriptive suffix.

e8945a8ce6 isaspec: Stop depending on glue headers and out-of-folder C files
The way the isaspec decoder used to work was that it would generate a
header and a C file, each with ISA-specific stuff in it. Then that would
get built together with a stand-alone decode.c file which lives in the
isaspec folder, not the driver's folder.  In order for decode.c to find
the ISA-specific headers, it would also generate a glue header which had
to be named isaspec-isa.h.  This effectively meant that you can't have
multiple isaspec definitions in the same folder.

To solve this, we make do it the other way around and make the generated
header and C files include the stand-alone files.  This is a bit awkward
because it means including a C file from another C file but it's better
for the build system.

1b8a43a0ba util: Remove util_cpu_detect
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.
