[DebugInfo][SimpleLoopUnswitch] Fix missing debug location updates (#97662)
Fix #97559 .
For the change at line 1253, I propagate the debug location of the
terminator (i.e., the insertion point) to the new phi. because `MergeBB`
is generated by splitting `ExitBB` several lines above, it only has the
terminator, which could provide a reasonable debug location.
For the change at line 2348, I switch the order of moving and cloning
`TI`. Because `NewTI` cloned from `TI` is inserted into the original
place where `TI` is, `NewTI` should preserve the origianl debug
location. At the same time, doing this allows us to propagate the debug
location to the new branch instruction replacing `NewTI` (the change at
line 2446).
