  [BranchFolding] Follow up #149999 crash fix

fbf6271c7da20356d7b34583b3711b4126ca1dbb introduced an assertion failure as
setDebugValueUndef was called on DBG_LABELs, which isn't allowed and doesn't
make sense. Fix by skipping the call for DBG_LABELs and hoisting, in line with
the original behaviour.
