If the driver said it can't do the shader, then listen to it and don't ask
it to create the shaders anyway. Fixes a bunch of spam on i915/r300 (with
!16878) about unsupported opcodes during dEQP runs.

according to the spec, atomic counters can be bound at any offset divisible by 4,
which means that any driver that uses the ssbo lowering pass and doesn't have
a min offset align of 4 is potentially broken
to handle this, use a statevar to inject the misaligned remainder of the offset
into the shader as a uniform. for well-aligned counter binds, the uniform offset
will be 0

Calling this directly in the linker code allows us to place it between
the varying linker and uniform linker calls which allows for better
optimisation/removal of uniforms.
Also in a later patch it allows us to insert a new nir based
lower_const_arrays_to_uniforms() call after the gl_nir_link_opts()
call. This is important because it allows the linking opts to
move constant arrays to later stages if possible before
lower_const_arrays_to_uniforms() turns them into uniforms.

The callback allows to request different vectorization factors
per instruction depending on e.g. bitsize or opcode.
This patch also removes using the vectorize_vec2_16bit option
from nir_opt_vectorize().

For example the SSO program may consist of just tcs -> gs or even
just a vs. In these cases we want to vectorise the externally
facing shader interfaces just like we would in non SSO programs.

Will allow us to drop more GLSL IR code in future once we switch
all drivers to NIR. Also stops the need for all drivers to call
this pass to remove indirect temps that may have been added during
the NIR varying linking lowering/optimisations.
This patch fixes some tests on i915, d3d12, lima and vc4.

since 1.0 is used in nearly every case, drivers requiring this exporting
can avoid potential shader variants by adding a 1.0 export to the base
shader variant and the only using the ubo upload when pointsize is explicitly
set for wide point functionality
drivers can then be responsible for removing unused pointsize exports
as needed (or desired)

The GLSL IR was previously used after converting to NIR for things
like building the GL resource list but we have had a NIR version
for this for some time and I don't believe there are any other
use cases left for keeping the old IR hanging around this long.

GLES2 drivers are allowed to reject some GLSL constructs, like dynamic
loop bounds (which neither i915g nor vc4 can fully support), but gallium
hasn't had any way to trigger a link failure. Add a return msg to the
finalize_nir hook, which is called at the end of GLSL linking, and use
that. This means that some other callers of finalize need to do something
with the msg, and we (for now) just throw it away.
