  Log Message:
  -----------
  [SimplifyCFG] Preserve metadata when unconditionalizing branches (constant condition).

When replacing a conditional branch by an unconditional one because the condition is a constant, transfer the metadata to the new branch instruction.

Part of fix for llvm.org/PR50060
