The SPIRV-LLVM-Translator seems to also set that cap for MSAA cl images,
but it looks like it works just fine in regards to LODs as well.

A loop that looks like:
loop {
do_work_1();
if (cond) {
break;
} else {
}
do_work_2();
break;
}
We can't pull that break ahead of do_work_1() after hoisting the initial
do_work_1() out of the loop. So bail in this case.

The static assert used in encode deref modes used the fact there was
less than 16 modes that we wanted to compress as an opportunity to reuse
MODE_ENC_GENERIC_BIT as it just happened to represent 16. However if we
add more than 16 modes i.e need to compress to 6 bits not 5 bits then
MODE_ENC_GENERIC_BIT becomes 32 and the logic in the assert breaks.
Instead we more precisely make sure MODE_ENC_GENERIC_BIT is large
enough to fit all but the last 4 generic modes and that the last 4 modes
defined in the enum are in fact the 4 generic modes.

Similar to commit 6cef804067 ("nir/opt_if: fix opt_if_merge when
destination branch has a jump"), we shouldn't combine if statements when
the second if-then-else has a block that ends in a jump.
This fixes a case where opt_if_merge combines
if (cond) {
[then-block-1]
} else {
[else-block-1]
}
if (cond) {
[then-block-2]
} else {
[else-block-2]
}
where `then-block-2` or `else-block-2` ends in a jump. The phi nodes
following the control flow will be incorrectly updated to have an input
from a block that is not a predecessor.

Phi nodes are mostly handled the same way as ALU instructions: if all
sources point to the same def (which happens if they are scalar or have
been previously vectorized), combine them into a single vectorized phi
node.
There is one case where this doesn't work, however: sources that come
from a loop back-edge. Since their defs haven't been processed yet, they
are generally not the same. We could simply refuse to vectorize such
phi nodes but this could leave many values used in loops unnecessarily
scalarized.
Instead, this patch implements a simple heuristic: if all defs coming
from a back-edge have the same instructions type and, in case of ALU,
the same operation, assume they will be vectorized later. Since we
require that normal edges are vectorized already, chances are that the
back-edge can also be vectorized.

To handle phi nodes, it's important that all sources have been processed
before processing the phi node itself. The current traversal order
(depth-first on dom_children) does not guarantee this. This patch
rewrites the pass to visit blocks in source-code order.
