In some cases nir_lower_int64 will emit fp64 operations which aren't
natively supported on any Intel hardware (e.g. ftrunc, frem). An
extra pass of nir_opt_algebraic (for frem) and nir_lower_doubles is
required in order to take care of them. This fixes several int64
test-cases on MTL hardware.

Again sharing the same function across all Intel drivers.
There is still two additional DRM_IOCTL_I915_GEM_CONTEXT_GETPARAM
calls, one in intel/dev and other in perf.
The first one can't call intel_gem_get_context_param() because of the
build order of libs and the second one because it sets the size
parameter.
Will revisit those calls in future but this is already an improvement.

nir_opt_large_constants balks at seeing a store_deref of a variable
where the source is a vecN operation of multiple load_consts, and thinks
that isn't a constant, so it should not bother promoting it.
Unfortunately, we were running nir_lower_load_const_to_scalar before
nir_opt_large_constants, so this prevented a ton of constant promotion.

When lowering a single instruction with a destination VGRF to 2 or
more, the VGRF is now considered partially written by each generated
instruction and that increases its liveness especially in loops. Thus
potentially increasing the number of spills/fills due to register
allocation.
Putting an UNDEF instruction in front of the lowered instructions
allows the IR to limit the liveness of the VGRF, reducing register
pressure.
This has a pretty dramatic effect on spills/fills for RT shaders. Here
the stats on Q2RTX shaders on DG2 (wipping out any spills/fills due to
register allocation) :
Instructions in all programs: 26150 -> 24955 (-4.6%)

NIR has two implementations of lower_idiv, keyed on the
imprecise_32bit_lowering flag. This flag is misleading: the results when
setting this flag "imprecise", they're completely wrong for some values.
If a backend has a native implementation of umul_high, the correct path
isn't that much more expensive. If it doesn't, it's substantially slower
for highp integer divison... but in practice, non-constant highp integer
division is pretty rare.
After a painful migration of the tree, this code path has no more users.
Remove it so nobody else gets the bright idea of using it again.
