[CodeGenPrepare] Check that erased sunken address are not reused CodeGenPrepare sinks address computations from one basic block to another and attempts to reuse address computations that have already been sunk. If the same address computation appears twice with the first instance as an operand of a load whose result is an operand to a simplifable select, CodeGenPrepare simplifies the select and recursively erases the now dead instructions. CodeGenPrepare then attempts to use the erased address computation for the second load. Fix this by erasing the cached address value if it has zero uses before looking for the address value in the sunken address map. This partially resolves PR35209. Thanks to Alexander Richardson for reporting the issue! This fixed version relands r318032 which was reverted in r318049 due to sanitizer buildbot failures.
