if the depth test is disabled, but depthCompareOp is VK_COMPARE_OP_NEVER

i965: expose type of memcpy instead of memcpy function itself

There is currently no use of returned memcpy functions outside
intel_tiled_memcpy. Patch changes intel_get_memcpy to return memcpy
type instead of actual function. This makes it easier later to separate
streaming load copy in to own static library.

mesa/st: Only call nir_lower_io_to_scalar_early on scalar ISAs

On scalar ISAs, nir_lower_io_to_scalar_early enables significant
optimizations. However, on vector ISAs, it is counterproductive and
impedes optimal codegen. This patch only calls
nir_lower_io_to_scalar_early for scalar ISAs. It appears that at present
there are no upstreamed drivers using Gallium, NIR, and a vector ISA, so
for existing code, this should be a no-op. However, this patch is
necessary for the upcoming Panfrost (Midgard) and Lima (Utgard)
compilers, which are vector.

With this patch, Panfrost is able to consume NIR directly, rather than
TGSI with the TGSI->NIR conversion.
