egl: Expose EGL_KHR_get_all_proc_addresses and its client extension

Mesa already implements the behavior of EGL_KHR_get_all_proc_addresses
and EGL_KHR_client_get_all_proc_addresses. This patch just exposes the
extension strings.

ir_to_mesa: Remove sat to clamp lowering pass

Fixes an infinite loop in swrast where the lowering pass unpacks saturate into
clamp but the opt_algebraic pass tries to do the opposite.

v3 (Ian):
This is a revert of commit cfa8c1cb "ir_to_mesa: lower ir_unop_saturate" on
the ir_to_mesa.cpp portion. prog_execute.c can handle saturates in vertex
shaders, so classic swrast shouldn't need this lowering pass.

st/mesa: For vertex shaders, don't emit saturate when SM 3.0 is unsupported

There is a bug in the current lowering pass implementation where we lower saturate
to clamp only for vertex shaders on drivers supporting SM 3.0. The correct behavior
is to actually lower to clamp only when we don't support saturate which happens
on drivers that don't support SM 3.0

radeonsi: Program RASTER_CONFIG for harvested GPUs v5

Harvested GPUs have some of their render backends disabled, so
in order to prevent the hardware from trying to render things
with these disabled backends we need to correctly program
the PA_SC_RASTER_CONFIG register.

v2:
  - Write RASTER_CONFIG for all SEs.

v3:
  - Set GRBM_GFX_INDEX.INSTANCE_BROADCAST_WRITES bit.
  - Set GRBM_GFX_INFEX.SH_BROADCAST_WRITES bit when done setting
    PA_SC_RASTER_CONFIG.
  - Get num_se and num_sh_per_se from kernel.

v4:
  - Get correct value for num_se
  - Remove loop for setting PA_SC_RASTER_CONFIG
  - Only compute raster config when a backend has been disabled.

v5: Michel Dänzer
  - Fix computation for chips with multiple SEs

winsys/radeon: Always report at least 1 compute unit

All uses of this require that the value be at least one, so it's
easier to report at least one than having to wrap all uses

We can avoid it by carefully ordering the packing.  This is important as a

vc4: Fix decision for whether the MIN operation writes to the B regfile.
vc4: Interleave register allocation from regfile A and B.

The register allocator prefers low-index registers from vc4_regs[] in the
configuration we're using, which is good because it means we prioritize
allocating the accumulators (which are faster).  On the other hand, it was
causing raddr conflicts because everything beyond r0-r2 ended up in
regfile A until you got massive register pressure.  By interleaving, we
end up getting more instruction pairing from getting non-conflicting
raddrs and QPU_WSes.
