This value is intended to be used to remove out of bounds array
access when unrolling loops so it should contain the comparison
that contains the the induction variable not the overall
condition of the loop terminator. So here we update the instruction
when dealing with iand/ior loop terminator conditions.

nir_lower_frag_coord_to_pixel_coord was adding .5 to work around that the
drivers were mistakenly setting PIXEL_COORD_HALF_INTEGER. With the
setting corrected, the GL frontend handles it appropriately (instead of
subtracting half in the frontend for ARB_fragment_coord_conventions
integer setting and then adding the half back here), and makes the pass
reusable from Intel.

This allows us to not generate 64-bit iadd3 on Intel but continue
generating it for NVIDIA.
No shader-db or fossil-db changes.
v2: Add nir_lower_iadd3_64 flag so we can continue to generate 64-bit
iadd3 on NVIDIA platforms.
v3: s/bit_size == 64/s == 64/. This cut-and-paste bug prevented any of
the optimizations from ever occuring.

For drivers that don't lower mediump shader inputs / outputs
to 16-bit, it's better to ignore the mediump flag completely,
letting mediump inputs / outputs work like normal 32-bit IO.

New pass that shares code with nir_opt_load_store_vectorize but
it only updates the alignment of load/store instructions.
It is useful before running other passes which may
potentially destroy that information (eg. by removing some

a substantial performance penalty. Actually, that's needed just to pass CTS
because of other hardware issues stacking on top of each others... Hooray!
