predecessors (#3211) * Add test case for while loop * Fix loop inversion issue that caused ordinary blocks with multiple predecessors The original version can leave the CFG in an invalid state with `e4` not being a break block or merge point, but having multiple predecessors.

2023-09-03Loop inversion: Handle case where loop can have additional inner breaks (#3178)Sai Praveen Bangaru
* Loop inversion: Handle case where loop can have additional inner breaks - We now have another critical-edge-breaking block `e4` that is the target of inner breaks. - Both `e4` and `e1` (the break branch from the loop condition) branch to the loop's ne break block `b2`. - `b2` is a clone of the old break block `b`, and it simply branches to the old break block. This fixes an IR validation issue in `tests/autodiff/reverse-while-loop-2.slang` * Delete region-wave-masks.slang --------- Co-authored-by: Yong He <yonghe@outlook.com>
