The intention here, long ago, was to ensure that any symbols the DRI
driver needed from libGL were available. We don't have this problem
anymore, libgallium does not import any symbols from the GLX frontend
(or any other one for that matter).

Since MR !33891 EGL only supports a software driver (LLVM).
Routine dri3_x11_connect at
src/egl/drivers/dri2/platform_x11.c fails if DRI3 is not
available. So at that location variable *allow_dri2 should be set.
Looking at the major codition, we see it is not executed
if LIBGL_DRI3_DISABLE is set. In that case the hardware driver
is activated as desired. Previously this was not needed.
Also it is not practical, and not necessary.
I do not understand the major condition, so I did not change it.
This causes some duplicate coding.

Allocate space for the aliased region first, then allocate the
non-Aliased blocks in sequence after that.
SPV_KHR_workgroup_memory_explicit_layout extension added support for
having Blocks of workgroup (shared) memory, which include layout
decoration. For that extension all such blocks must be decorated with
Aliased.
SPV_KHR_untyped_pointers extension lifts that requirement, allowing
blocks that don't alias in workgroup memory. They are still explicitly
laid out.
The motivation is that untyped pointers provide a different
mechanism to obtain the same effect as the Aliased blocks. Instead of
having two Aliased variables with different types, have a single
variable and use an untyped pointer with a different type to access it.
This patch is a preparation for supporting untyped pointers.

Move the calculation to nir_lower_vars_to_explicit_types(). This
consolidates the check of shader_info::shared_memory_explicit_layout
in a single place instead of in all drivers.
This is motivated by SPV_KHR_untyped_pointers. Before that extension
we had essentially two modes for shared memory variables
- No layout decorations in the SPIR-V, and both internal layout and
driver location was _given by the driver_.
- Explicitly laid out, i.e. they are blocks, and decorated with Aliased.
Because they all alias, we could assign them driver location directly
to the start of the shared memory.
With the untyped pointers extension, there's a third option, to be added
by a later commit
- Explicitly laid out, i.e. they are blocks, and NOT decorated
with Aliased. Driver location is _given by the driver_. Blocks
with and without Aliased can be mixed.
The driver location of multiple blocks that don't alias depend on
alignment that is driver-specific, which we can more easily do from
the nir_lower_vars_to_explicit_types() that already has access to
a function to obtain such value.

This is now basically the same as the original VALUMaskWriteHazard, except
it now considers both VALU and SALU writes.
Now that it's a part of VALUMaskWriteHazard, differences from the original
VALU lanemask workaround are:
- it includes SALU reads after the write
- it includes VALU writes and SALU/VALU reads after the write which are
not lanemasks
- it combines s_waitcnt_depctr instructions when it's a read after both a
SALU write and a VALU write
- non-exec VALU SGPR reads reset the SGPRs read by VALU as a lanemask
- exec SGPRs are ignored
resolve_all_gfx11() is also finished.

In a previous iteration of the spilling code, we added an extra check to
only spill across edges if the value being spilled is in the W set.
This was due to a misunderstanding of the modeling of S and W in Braun
and Hack. In the current implementation, we maintain the invariant that
every live value is in at least one of S or W so we don't need that
check but it was left in by mistake.
One exception to this rule was added when we special-cased constant
values. Now the invariant is that every live value is in S, in W, or is
a constant. When we made this change, the check we accidentally left in
bit us because now if a value is constant but not in W, it wasn't
getting spilled across the edge. This can result in a value getting
filled later which was never spilled, leading to undefined values.
