Potential infinite loop in MemorySSAUpdater
...o cases we will hvae inserted phis:
Part of the recursive call, or right in this function.
The easiest way to differentiate new phis from old ones is whether they
have 0 operands.
I expect the attached will fix it.
If not, please file a bug with reproducible IR.

...shold=1000 and -enable-gvn-hoist” options is looping infinitely on the above loop.
Above loop never terminates unless elements from InsertedPHIs are removed as and when they are processed. But, I don’t see any call to remove contents, delete or clear, from InsertedPHIs.
