Fix pessimization in EH cleanup pass
This restores the post-order traversal done by cleanup_all_empty_eh in
order to eliminate empty landing pads and also contains a small tweak
to the line debug info to avoid a problematic inheritance for coverage
measurement.
gcc/ChangeLog:
* tree-eh.c (lower_try_finally_dup_block): Backward propagate slocs
to stack restore builtin calls.
(cleanup_all_empty_eh): Do again a post-order traversal of the EH
region tree.
gcc/testsuite/ChangeLog:
* gnat.dg/concat4.adb: New test.
