lima/ppir: mark regalloc created ssa unspillable

One ssa created in the spillinc code in ppir_update_spilled_src was not
properly being marked 'spilled', which made it a candidate for future
spilling attempts.
Since it was being inserted by the spilling code itself, let's mark it
unspillable to avoid an infinite spilling loop.

Case can be catched with steps:

3. Make egl as current

glx: Fix SEGV due to dereferencing a NULL ptr from XCB-GLX.

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.

lima/ppir: clone uniforms and load_coords into each successor

Try more aggressive approach with cloning uniform and coord loads.

Uniform load can be inserted into any instruction, so let's do that. ARM site
claim that penalty for cache miss is one clock, so we don't lose anything if
we merge it into instruction that uses the result. As side effect we can also
pipeline it and thus decrease reg pressure.

Do the same for varyings that hold texture coords, but for different reason:
looks like there's a special path for coords that increases precision if
varying that holds it is pipelined. If we don't pipeline it and load coords
from a register its precision is fp16 and thus only 10 bits which is not enough
to accurately sample textures of size 1024 or larger.

Since instruction can hold only one uniform load and one varying load,
node_to_instr now creates a move using helper introduced in previous commit if
slot is already taken. As side effect of this change we can also try to
pipeline texture loads and create a move if attempt fails.

iris: Lessen texture cache hack flush for blits/copies on Icelake.

Lionel found actual documentation for this at long last.  Apparently
it actually is a sampler cache limitation that was mostly fixed on
Icelake.  Unfortunately, it seems there are still issues with ASTC
and non-ASTC sampler views.  Still, we can lessen the flush condition
from "format mismatch" to "ASTC mismatch", which eliminates most of
the flushing here.

We also update the documentation to refer to the workaround name.
