James Molloy 1a9f29f7eb [SimplifyCFG] Update (AND) IR flags when CSE'ing instructions 
We were updating metadata but not IR flags. Because we pick an arbitrary instruction to be the CSE candidate, it comes down to luck (50% or less chance) if this results in broken codegen or not, which is why PR30373 which is actually not the fault of the commit it was bisected down to.

Fixes PR30373.
