  Log Message:
  -----------
  [LICM] Add test showing incorrectly setting alasing metadata.

The new test illustrates a case where LICM introduces UB-implying
metadata on speculated loads that may not execute in the original
version.

The aliasing metadata behavior has been clarified in
 https://github.com/llvm/llvm-project/pull/116220.
