mesa/st: Add support for SPIR-V shaders

The SPIR-V codepath uses NIR linking, so we have to preprocess after
the linking steps, which makes things slightly different than GLSL.
To make more clear when the preprocess is happening, I've ended up
inlining st_nir_get_mesa_program() into its caller.

The goal was to make both GLSL and SPIR-V to use the same preprocess
function, the exceptions are:

- SPIR-V codepath don't support NIR state slots yet;
- GLSL lowers shared memory early, so we don't do the deref lowering
  for those.

For now I didn't bother to rename other functions and files (now that
many of them apply to both GLSL and SPIR-V), but we should do this in

iris: Avoid flushing for cache history on transfer range flushes

The VBO module maps a buffer with GL_MAP_FLUSH_EXPLICIT, and keeps
appending data, and calling glFlushMappedBufferRange().  We were
invalidating the VF cache each time it flushed a new range, which
results in a ton of VF flushes.

If the contents of the destination in the target range are undefined
(never even possibly written), this patch makes us assume that it's
likely not in the cache and so cache invalidations are required.  If
the destination range is defined, we continue cache flushing as we may
need to expunge stale data.

This eliminates 88% of the VF cache invalidates on Manhattan 3.0.
Improves performance in Manhattan 3.0 on my Icelake 8x8 with the GPU
frequency locked to 700Mhz by 0.376724% +/- 0.0989183% (n=10).

iris: Optimize out redundant sampler state binds

This cuts roughly 85% of the 3DSTATE_SAMPLER_STATE_POINTERS_PS calls in
the J2DBench images test.  For some reason, the state tracker is calling
bind_sampler_state with the same sampler state in a bunch of cases.

iris: Add support for the always_flush_cache=true debug option.

This can be useful for debugging missing flushes.

gallium/xlib: Fix an obvious thinko

x == !GLX_DIRECT_COLOR is a fancy way of writing x == 0, which is

iris: Ignore line stipple information if it's disabled

The line stipple pattern and factor only matter if line stippling is
actually enabled.  Otherwise, we can safely ignore it.

PBO upload may give us zero for line stipple information, while normal
drawing tends to give us an actual stipple pattern such as 0xffff.  This
was causing us to flag IRIS_DIRTY_LINE_STIPPLE way too often, leading to
useless 3DSTATE_LINE_STIPPLE commands, which are non-pipelined and thus
very expensive.
