[licm] clone `MD_prof` when hoisting conditional branch (#152232)

The profiling - related metadata information for the hoisted conditional branch should be copied from the original branch, not from the current terminator of the block it's hoisted to.

The patch adds a way to disable the fix just so we can do an ablation test, after which the flag will be removed. The same flag will be reused for other similar fixes.

(This was identified through `profcheck` (see Issue #147390), and this PR addresses most of the test failures (when running under profcheck) under `Transforms/LICM`.)
