NIR currently assumes that unreachable blocks are trivially dominated by
everything. However, when considering well-formed SSA, there is no path
from any block to an unreachable block. Therefore, we can break any
use-def chains where the use is in an unreachable block. This removes
any dependencies on code created by uses in unreachable blocks and lets
DCE do a better job of cleaning it up.

This fixes SIMD32 fragment shaders which broke because lower_simd_width

KWin was able to get NULL-context in the call
intelUnbindContext. But a call _mesa_glthread_finish
is not resistent to such case.
Case can be catched with steps:
1. Create both glx and egl contexts
2. Make glx as current
3. Make egl as current
4. Reset glx context
5. Make egl as current
Solution adds proper finishing of glthread-context
(context will be taken from the requested dri-context
for unbinding, but not from the saved current context).

(cherry picked from commit 3f5b541fc8)
When run in optirun, applications that linked to `libGLX.so` and then
proceeded to querying Mesa for extension strings caused a SEGV in Mesa.
`glXQueryExtensionsString` was calling a chain of functions that
eventually led to `__glXQueryServerString`. This function would call
`xcb_glx_query_server_string` then `xcb_glx_query_server_string_reply`.
The latter for some unknown reason returned `NULL`. Passing this `NULL`
to `xcb_glx_query_server_string_string_length` would cause a SEGV as the
function tried to dereference it.
The reason behind the function returning `NULL` is yet to be determined,
however, simply checking that the ptr is not `NULL` resolves this. A
similar check has been added to `__glXGetString` for completeness sake,
although not immediately necessary.
In addition to that, we stumbled into a similar problem in
`AllocAndFetchScreenConfigs` which tries to access the configs to free
them if `__glXQueryServerString` fails. This, of course, SEGVs, because the
configs are yet to have been allocated. Simply continuing past the configs
if their config ptrs are `NULL` resolves this. We also switch to `calloc`
to make sure that the config ptrs are `NULL` by default, and not some
uninitialized value.

The majority of these only apply the start argument to the input, but a
few of them also does for the output-array. util_primconvert, the only
user of this argument expects this pass a non-zero start-argument does
not expect this to be applied to the output; if it is, it will write
outside of allocated memory, leading to VRAM corruption.
The reason this doesn't seem to have been noticed before, is that no
driver currently use util_primconvert to convert a primitive-type to
itself, which is the cases where this was broken. But for Zink, this
will no longer be true, because we need to eliminate the use of 8-bit

This caused a problem on Sandybridge where an open-coded
bitfieldReverse() function could be optimized to a
nir_op_bitfield_reverse that would generate an unsupported BFREV
instruction in the backend. This was encountered in some Unreal4 tech
demos in shader-db. The bug was not previously noticed because we don't
actually try to run those demos on Sandybridge.
The fixes tag is a bit a lie. The actual bug was introduced about
26,000 commits earlier in 371c4b3c48 ("nir: Recognize open-coded
bitfield_reverse."). Without the NIR lowering pass, the flag needed to
avoid the optimization does not exist. Hopefully nobody will care to
fix this on an earlier Mesa release.

src0 vstride and type overlap with bits of the extended descriptor.
brw_set_desc() also sets the extended descriptor to 0. So by setting
the descriptor, then setting src0, we were accidentally setting a bunch
of extended descriptor bits unintentionally.
When using this infrastructure for framebuffer writes (in a future
patch), this ended up setting the extended descriptor bit 20, which is
"Null Render Target" on Icelake, causing nothing to be written to the
framebuffer.

This fixes the following CTS test on 32-bit systems:
GTF-GL46.gtf30.GL3Tests.packed_depth_stencil.packed_depth_stencil_init
It does glGetTexImage of a 16-bit SNORM image, requesting 32-bit UNORM
data. In get_tex_rgba_uncompressed, we round trip through float to
handle image transfer ops for clamping. _mesa_format_convert does:
_mesa_float_to_unorm(0.571428597f, 32)
which translated to:
_mesa_lroundevenf(0.571428597f * 0xffffffffu)
which produced different results on 64-bit and 32-bit systems:
64-bit: result = 0x92492500
32-bit: result = 0x80000000
This is because the size of "long" varies between the two systems, and
0x92492500 is too large to fit in a signed 32-bit integer. To fix this,
we switch to the new _mesa_i64roundevenf function which always does the
64-bit operation.

This doesn't work for compressed formats, as the source texture and

the source format for the temporary, and let blorp_copy deal with
overrides.
The one case where we can't do this is ASTC, because isl won't let us

For renderable surfaces, we allocate SURFACE_STATEs for each bit in
res->aux.possible_usages. Sampler views use res->aux.sampler_usages.
When pinning buffers, we call surf_state_offset_for_aux() to calculate
the offset to the desired surface state. surf_state_offset_for_aux()
took an aux_modes parameter, which should be one of those two fields.
However...it was not using that parameter. It always used the broader
res->aux.possible_usages field directly.
One of the callers, update_clear_value(), was passing incorrect masks
for this parameter. It iterated through the bits in order, using
u_bit_scan(), which destructively modifies the mask. So each time we
called it, the count of bits before our selected mode was 0, which would
cause us to always update the SURFACE_STATE for ISL_AUX_USAGE_NONE,
rather than updating each in turn. This was hidden by the earlier bug
where surf_state_offset_for_aux() ignored the parameter.
