Hi @davemgreen 
Some tests are failing in one of our internal test suites. I have reduced the test to the IR: https://godbolt.org/z/a4W18rdsn

The phi node is getting replaced with a branch that eventually leads to an infinite loop. The test run faults with "Invalid Instruction" on Neoverse-V2 platform.

Can you please have a look and let me know if this can be fixed?
