We don't do full dominance validation of SSA values in nir_validate
because it requires generating valid dominance information and, while
that's not extremely expensive, it's probably more than we want to do on
every pass. Also, dominance information is generated through the
metadata system so if we ran it by default in nir_validate, we would get
different beavior of the metadata system based on whether or not you
have a debug build and metadata bugs would be very hard to find.
However, having a pass for it that can be run occasionally, should help
detect and expose bugs. For ease of use, we add a NIR_VALIDATE_SSA_DOMINANCE
environment variable which can be set to manually enable dominance
validation as a standard part of nir_validate.

Fixes a case where opt_if_merge created code like:
if (...) {
break;
loop {
...
}
}
which caused opt_peel_loop_initial_if to complain that the loop pre-header
wasn't a predecessor of the loop header. This patch prevents this
(invalid, I think) unreachable code from being created.

There's no sense in planning out an upload that we won't be able to
actually upload due to the limit. This means that we can keep making
other loads pushable, even after we find one that wouldn't be, and we
don't fill the const file with UBO data for a load we couldn't promote.

Now that NIR doesn't lose the original base/range on the

For UBO accesses to be the same performance as classic GL default uniform
block uniforms, we need to be able to push them through the same path. On
freedreno, we haven't been uploading UBOs as push constants when they're
used for indirect array access, because we don't know what range of the
UBO is needed for an access.
I believe we won't be able to calculate the range in general in spirv
given casts that can happen, so we define a [0, ~0] range to be "We don't
know anything". We use that at the moment for all UBO loads except for
nir_lower_uniforms_to_ubo, where we now avoid losing the range information
that default uniform block loads come with.
In a departure from other NIR intrinsics with a "base", I didn't make the
base an be something you have to add to the src[1] offset. This keeps us
from needing to modify all drivers (particularly since the base+offset
thing can mean needing to do addition in the backend), makes backend
tracking of ranges easy, and makes the range calculations in
load_store_vectorizer reasonable. However, this could definitely cause
some confusion for people used to the normal NIR base.

The current align_mul calculation in the unknown-array-index
calculation is
align_mul = MIN3(parent_mul,
min_pow2_divisor(parent_offset),
min_pow2_divisor(stride))
which is certainly correct if parent_offset > 0. However, when
parent_offset = 0, min_pow2_divisor(parent_offset) isn't well-defined
and our calculation for it is 1 << -1 which isn't well-defined. That
said.... it's not actually needed.
The offset to the base of the array is
array_base = parent_mul * k + parent_offset
for some integer k. When we throw in an unknown array index i, we get
elem = parent_mul * k + parent_offset + stride * i.
If we set new_align = MIN2(parent_mul, min_pow2_divisor(stride)), then
both parent_mul and stride are divisible by new_align and
elem = (parent_mul / new_alig) * new_align * k +
(stride / new_align) * new_align * i + parent_offset
= new_align * ((parent_mul / new_alig) * k +
(stride / new_align) * i) + parent_offset
so elem = new_align * j + parent_offset where
j = (parent_mul / new_alig) * k + (stride / new_align) * i.
That's a very long-winded way of saying that we can delete one parameter
from the align_mul calculation and it's still fine. :-)
