spirv_to_nir sometimes wraps derefs in vec2 or mov instructions as part of
its texture handling. These get in the way of
nir_rematerialize_derefs_in_use_blocks_impl. Running copy propagation
should get rid of the extra move instructions and get us back to intact
deref chains for everything except variable pointer use-cases.

This function is big and I don't think it will won't get meaningfully
constant-propagated during inlining without LTO. Move it to a .c file so
we just have one copy, saving 2.8MB from libnir.a on an amd64 release

Pattern match the point coord sysval and support lowering it as well.
This is required to handle flipped framebuffers on Bifrost. However,
what this pass normalizes to is the opposite of the hardware mode we
used on Bifrost before, so we need to swap modes at the same time to
prevent regressions.

The GLSL spec says it's an error if a shader statically writes to these
2 variables.
Until this commit, Mesa refused to link a shader if it had an unused
function writing to one of these variables while another (used) function
wrote to the other.
This commit adds an option to perform dead function elimination after
the intra-stage linking step but before performing these checks.

nir_lower_blend was written against the OpenGL ES 3.2 specification,
which does not support blending SNORM render targets. The ES spec
says that non-floating point buffers get clamped to [0, 1] before
blending. The story is not so simple: SNORM buffers are blendable in
OpenGL and must clamped to [-1, 1] rather than [0, 1]. Handle this case.
NIR does have the fsat_signed_mali instruction to clamp to [-1, 1], but
it is only implemented in Panfrost, and this pass is in common code.
Open code it instead. Panfrost optimizes the open coded version, so this
is good enough.
