1c82c05d58 gallivm: run nir_opt_algebraic_late
Without this, we're left with a bunch of medium-precision residue, like
i2imp. And to avoid that the lowering intrudces left-over instructions,
also run other lowering passes, similar to what other drivers do.

fcebdcb3b3 panfrost: Fix Bo imports to not take the process down if fd is invalid
If the calling process happens to use an invalid bo (e.g. fd has been
closed), this led to lseek() returning -1 and this mmap trying to mmap
a buffer of size -1 (0xffffffffffffffff ...) which led to mmap
failing, which led to munmap failing which then led to the process
aborting.

This fixes that to gracefully handle the mmap failures and percolate
the failures back up through the API so eglCreateImage will not return
a valid image anymore, thus the error is detectable in the caller
process too.

750ddf3239 gallium/hud: extend check for has_srgb
gallium hud checks for the PIPE_FORMAT_B8G8R8A8_SRGB format to set
has_srgb, but can then receive a different format such as
PIPE_FORMAT_B8G8R8X8 in hud_run.
If the driver supports PIPE_FORMAT_B8G8R8A8_SRGB but does not support
the other formats such as PIPE_FORMAT_B8G8R8X8_SRGB, that will break
rendering as gallium hud assumes srgb is also supported for that format.
Extend the check to set has_srgb to prevent that from happening.

f93dc9dc77 gallium/hud: create vs_text to match fs_text
gallium hud uses different tgsi fragment shaders for text and background
quads, which have different varying layouts. Since these are compiled
directly from tgsi they bypass some optimizations and may not work
properly on all backends.
A simple fix for the varying layout problem is to define a vs_text
shader to match the varyings in fs_text so the problem is avoided.

5de3cbbb2e nir: Generate load_ubo_vec4 directly for !PIPE_CAP_NATIVE_INTEGERS
The prog_to_nir->NIR-to-TGSI change ended up causing regressions on r300,
and svga against r300-class hardware, because nir_lower_uniforms_to_ubo()
introduced shifts that nir_lower_ubo_vec4() tried to reverse, but that NIR
couldn't prove are no-ops (since shifting up and back down may drop bits),
and the hardware can't do the integer ops.

Instead, make it so that nir_lower_uniforms_to_ubo can generate
nir_intrinsic_load_ubo_vec4 directly for !INTEGER hardware.

Fixes: cf3fc79cd0 ("st/mesa: Replace mesa_to_tgsi() with prog_to_nir() and nir_to_tgsi().")
Closes: #4602
