gcc: backport two patches to fix ICE in dwarf2out_var_location

The first patch fixes the ICE in dwarf2out_var_location, at
dwarf2out.c.

r212171:
    * except.c (emit_note_eh_region_end): New helper function.
    (convert_to_eh_region_ranges): Use emit_note_eh_region_end to
    emit EH_REGION_END note.
    * jump.c (cleanup_barriers): Do not split a call and its
    corresponding CALL_ARG_LOCATION note.

But it introduced a regression issue:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63348

so backport the fix for the regression as well:

r215613:
    PR rtl-optimization/63348
    * emit-rtl.c (try_split): Do not emit extra barrier.
