It's undefined behavior in C to read a union member if another member
has been written to more recently. Let's be more careful here!

6698753cdb switched our GS output stores to use MUBUF.
The stride doesn't matter for the ESGS descriptor (because idxen=false and
the index stride is 64), but this fixes it anyway.
This also changes ACO to use MUBUF store too, since MTBUF doesn't seem to
work correctly with an invalid data format in the descriptor.

Recently, a regression was reported where videos in Firefox had shifted/
glitched colors on certain Kepler hardware. This was bisected to
bf02bffe15, however, the issue already
existed but didn't hit users until TGSI was switched to NIR as default.
The issue was traced to a YUV-to-RGB fragment shader used by Firefox,
which uses three samplers for the Y/U/V components. The Y component was
handled correctly, but the U/V components were bogus, causing the issue.
After analysis, it appears the TXF/TXQ ops. should only handle the texture
(r) but not the sampler (s), see 63b850403c
and 346ce0b988.
Similarly, handleTXQ/handleTXF on nv50_ir_from_tgsi always sets s=0.
Only Kepler was affected because other hardware ignores s at codegen.
Always set s=0 on NIR for TXF/TXQ, to keep TGSI behavior and fix the
regression.
Thanks: Karol Herbst and M Henning for help diagnosing the issue.

Documentation is worded in a confusing way, which may be understood that
we don't have to set this field to get good results.

Add unit tests for debug_get_bool_option and debug_get_num_option
Merge env_var_as_boolean and debug_get_bool_option and implement
env_var_as_boolean with debug_get_bool_option in a stricter side.
Merge env_var_as_unsigned and debug_get_num_option and implement
env_var_as_unsigned with debug_get_num_option in a stricter side.
Move debug_control, parse_debug_string, parse_enable_string,
comma_separated_list_contains from debug.* to u_debug.*
Main changes:
os_get_option() is used instead of getenv() for env_var_as_boolean
and env_var_as_unsigned;
also debug_get_bool_option() has logic like "true" always if not "false";
env_var_as_boolean() now uses different logic:
if env variable is neither "true" nor "false" returns the default value,
we left the second one; but if you want the behavior to be the same as in
the old version of debug_get_bool_option() use dfault=true

This does the exact opposite of 06e96074 from !16129.
Before LLVM commit 702d5de4 opaque pointers were supported but not enabled
by default when building LLVM. They were made default in commit 702d5de4.
LLVM commit d69e9f9d introduced -opaque-pointers/-no-opaque-pointers cc1
options to enable or disable them whatever the LLVM default is.
Those two commits follow llvmorg-15-init and precede llvmorg-15.0.0-rc1 tags.
Since LLVM commit d785a8ea, the CLANG_ENABLE_OPAQUE_POINTERS build option of
LLVM is removed, meaning there is no way to build LLVM with opaque pointers
enabled by default.
It was said at the time it was still possible to explicitly disable opaque
pointers via cc1 -no-opaque-pointers option, but it is known a later commit
broke backward compatibility provided by -no-opaque-pointers as verified with
arbitrary commit d7d586e5, so there is no way to use opaque pointers starting
with LLVM 16.
Those two commits follow llvmorg-16-init and precede llvmorg-16.0.0-rc1 tags.
Since Mesa commit 977dbfc9 opaque pointers are properly implemented in Clover
and used.
If we don't pass -opaque-pointers to Clang on LLVM versions supporting opaque
pointers but disabling them by default, there will be an API mismatch between
Mesa and LLVM and Clover will not work.

This reverts commit 06e9607478 from !16129.
Clover passed -no-opaque-pointers option to Clang to workaround the fact
the Clover code was not ported to opaque pointers yet.
Opaque pointers are now implemented thanks to !19103 so passing this
option to tell Clang to not do opaque pointers while Clover does
is actually breaking Clover.
Here is an example of what happens when using opaque pointers while
passing -no-opaque-pointers at the same time:
fatal error: cannot open file 'hawaii-amdgcn-mesa-mesa3d.bc':
Opaque pointers are only supported in -opaque-pointers mode
This fixes one of the last remaining bits to fully support opaque pointers
in Mesa as referenced in #7468, this is the last remaining bit to fully support
opaque points in Clover.
