path solver: Default to global range if nothing found.
This has been a long time coming, but we weren't able to make the
change because of some unrelated regressions.
Tested on x86-64 & ppc64le Linux.
gcc/ChangeLog:
* gimple-range-path.cc (path_range_query::internal_range_of_expr):
Default to global range if nothing found.
gcc/testsuite/ChangeLog:
* g++.dg/tree-ssa/pr31146-2.C: Add -fno-thread-jumps.
