[SFN] Introduce -gstatement-frontiers option, enable debug markers
Introduce a command line option to enable statement frontiers, enabled
by default in optimized builds with DWARF2+ debug information.
This patch depends on an earlier patch that completed the
infrastructure for debug markers, and on another patch that turns -g
into a negatable option prefix.
for gcc/ChangeLog
* common.opt (gstatement-frontiers): New, setting
debug_nonbind_markers_p.

frontiers option.
