rtl-ssa: Fix bug in function_info::add_insn_after
In the case that !insn->is_debug_insn () && next->is_debug_insn (), this
function was missing an update of the prev pointer on the first nondebug
insn following the sequence of debug insns starting at next.
This can lead to corruption of the insn chain, in that we end up with:
insn->next_any_insn ()->prev_any_insn () != insn
in this case. This patch fixes that.
gcc/ChangeLog:
* rtl-ssa/insns.cc (function_info::add_insn_after): Ensure we
update the prev pointer on the following nondebug insn in the
case that !insn->is_debug_insn () && next->is_debug_insn ().
