This should do much more trimming than shrink_load, and is a win on i965's
vec4 and nir-to-tgsi. For scalar backends like this that don't need ALU
shrinking, it still gets more load intrinsics covered.

This information is exposed through shader->options->lower_int64_options.
Removing the extra arg forces drivers to initialize this field correctly.
This also allows us to check the int64 lowering options from each int64
lowering helper and decide if we should lower the instructions we
introduce.

Previously, we've set element_size == 16 which causes loads from
packed vec3 arrays to cross the boundary and return wrong data.
This patch sets element_size = 4 and splits loads into single channel.
Fixes all of dEQP-VK.subgroups.ballot_broadcast.*

SMEM does the addition with 64-bits, not 32. So if the original code
relied on wrapping around (for example, for subtraction), it would break.
Apparently swizzled MUBUF accesses also have issues with combining
additions that could overflow. Normal MUBUF accesses seem fine.
