Two threads enter and see *id == 0. Both threads update the value.
Upon returning, one of the threads might see the overwritten value some
of the time and the updated value other times. Use cmpxchg to ensure
that there's only ever one value written to *id.

There are two problems with the current architecture.
In OpenGL, the id is supposed to be a unique identifier for a particular
log source. This is done so that applications can (theoretically)
filter particular log messages. The debug callback infrastructure in
Mesa assigns a uniqe value when a value of 0 is passed in. This causes
the id to get set once to a unique value for each message.
By passing a stack variable that is initialized to 0 on every call,
every time the same message is logged, it will have a different id.
This isn't great, but it's also not catastrophic.
When threaded shader compiles are used, the id *pointer* is saved and
dereferenced at a possibly much later time on a possibly different
thread. This causes one thread to access the stack from a different
thread... and that stack frame might not be valid any more. :(
I have not observed any crashes related to this particular issue.

Both Panfrost and the DDK add padding zero bytes to the end of
shaders, so we can use this instead of the end-of-shader clause for
checking whether to stop disassembling.
Shaders can have end-of-shader clauses partway through; these shaders
will now be completely disassembled instead of cut off at the first
end-of-shader clause.
A tag byte of zero is an invalid encoding, so unlike the previous
version of this test only check the first word.

The existing code handled the case where the new definition of the
same field was larger than the old one.
This commit adds a check to handle the reverse case: the new def
is smaller than the old one (= so writing using the merged macro
would affect the next fields).
The affected fields are:
* LGKM_CNT (in SQ_WAVE_IB_STS)
* DONUT_SPLIT (in VGT_TESS_DISTRIBUTION)
* HEAD_QUEUE (in GDS_GWS_RESOURCE)
DONUT_SPLIT is the only one used by radeonsi/radv.

This is much more maintainable, extensible, and easy to read than
hand-rolled structs approximating assembly. This also removes the last
use of the old hand-written packing structs. There are a few minor
differences:
- The shaders are larger because ir3 currently doesn't support (rpt),
which means that some shaders are larger than one instrlen and the
current logic has to be extended to allow for that. This seems a small
price to pay, ir3 will gain support for (rpt) eventually, and we
shouldn't have limitations like this baked in anyway. For example some
GL blob r8g8 <-> r16 copy shaders are apparently quite large.
- Due to the inability to switch inputs/outputs on the fly, we need to
split the VS into two variants. I made the layer-writing variant also
used for other clears, because the old method of overloading c0.z/c1.z
to mean both "src x coordinate" and "z clear value" in the same shader
seemed too clever and I didn't want to add yet another variant. This
means that non-layered clears will also write the layer (to 0), but
that shouldn't be a big deal performance-wise.

A previous commit cleaned up the asserts but the last part of
this assert looks like it got mixed up. It should have allowed
param->rel for D3DSPR_INPUT if version is 3.0. Instead it does
&& on the enum value D3DSPR_ADDR which is of course always true,
with the version check. The result is that we miss input
