backthreader dump fixlinaro-local/ci/tcwg_kernel/gnu-master-arm-stable-allmodconfig
This fixes odd SUCCEEDED dumps from the backthreader registry that
can happen even though register_jump_thread cancelled the thread
as invalid.
* tree-ssa-threadbackward.cc (back_threader::maybe_register_path):
Check whether the registry register_path rejected the path.
(back_threader_registry::register_path): Return whether
register_jump_thread succeeded.
