Avoid using unavailable objects in jt_state.
The jump threading state is about to get more interesting, and it may
get with a ranger or with the const_copies/etc helpers. This patch
makes sure we have an object before we attempt to call push_marker or
pop_to_marker.
Tested on x86-64 Linux.
gcc/ChangeLog:
* tree-ssa-threadedge.c (jt_state::push): Only call methods for
which objects are available.
(jt_state::pop): Same.
(jt_state::register_equiv): Same.
(jt_state::register_equivs_on_edge): Same.
