[-fcompare-debug] skip more debug stmts in cleanup_empty_eh
Various Ada RTS files failed -fcompare-debug compilation because debug
stmts prevented EH cleanups from taking place. Adjusting
cleanup_empty_eh to skip them fixes it.
for gcc/ChangeLog
* gimple-iterator.h (gsi_one_nondebug_before_end_p): New.
* tree-eh.c (cleanup_empty_eh): Skip more debug stmts.
