tree-optimization/111465 - bougs jump threading with no-copy src block
The following avoids to forward thread a path with a EDGE_NO_COPY_SRC_BLOCK
block that became non-empty due to folding.
PR tree-optimization/111465
* tree-ssa-threadupdate.cc (fwd_jt_path_registry::thread_block_1):
Cancel the path when a EDGE_NO_COPY_SRC_BLOCK became non-empty.
* g++.dg/torture/pr111465.C: New testcase.
