Optimize the result of a conditional break/continue. In NIR something
like:
loop {
...
if (cond)
continue;
would get lowered to:
block_0:
...
block_1:
branch_cond !cond block_3
block_2:
branch_uncond block_0
block_3:
...
We recognize the conditional branch skipping over the unconditional
branch, and turn it into:
block_0:
...
block_1:
branch_cond cond block_0
block_2:
block_3:
