* tree-ssa-threadedge.c (thread_across_edge): Make path a pointer to
a vec. Only delete the path if we create one without successfully
registering a jump thread.
* tree-ssa-threadupdate.h (register_jump_thread): Pass in path vector
as a pointer.
* tree-ssa-threadupdate.c (threaded_edges): Remove. No longer used
(paths): New vector of jump threading paths.
(THREAD_TARGET, THREAD_TARGET2): Remove accessor macros.
(THREAD_PATH): New accessor macro for the entire thread path.
(lookup_redirection_data): Get intermediate and final outgoing edge
from the thread path.
(create_edge_and_update_destination_phis): Copy the threading path.
(ssa_fix_duplicate_block_edges): Get edges and block types from the
jump threading path.
(ssa_redirect_edges): Get edges and block types from the jump threading
path. Free the path vector.
(thread_block): Get edges from the jump threading path. Look at the
entire path to see if we thread to a loop exit. If we cancel a jump
thread request, then free the path vector.
(thread_single_edge): Get edges and block types from the jump threading
path. Free the path vector.
(thread_through_loop_header): Get edges and block types from the jump
threading path. Free the path vector.
(mark_threaded_blocks): Iterate over the vector of paths and store
the path on the appropriate edge. Get edges and block types from the
jump threading path.
(mark_threaded_blocks): Get edges and block types from the jump
threading path. Free the path vector.
(thread_through_all_blocks): Use the vector of paths rather than
a vector of 3-edge sets.
(register_jump_thread): Accept pointer to a path vector rather
than the path vector itself. Store the path vector for later use.
Simplify.
