[ARM][MachineOutliner] Emit more CFI instructions
This patch make the outliner emit CFI instructions in a few more
places:
* after LR is restored, but before the return in an outlined
function
* around save/restore of LR to/from a register at calls to outlined
functions
* around save/restore of LR to/from the stack at calls to outlined
functions
The latter two only when the function does NOT spill LR. If the
function spills LR, then outliner generated saves/restores around
calls are not considered interesting for unwinding the frame.
