* rtl-factoring.c : Add sequence abstraction algorithm.
* cfgcleanup.c (outgoing_edges_match): Extra checks.
(try_crossjump_to_edge): Avoid deleting preserve label when redirecting
ABNORMAL edges.
(block_has_preserve_label): New function.
* common.opt: Register new pass.
* Makefile.in: Ditto.
* passes.c: Ditto.
* timevar.def: Ditto.
* tree-pass.h: Ditto.
* emit-rtl.c (make_jump_insn_raw): Remove forward decl.
* rtl.h (make_jump_insn_raw): Add forward decl.
* doc/invoke.texi: Add documentation for
-frtl-abstract-sequences.
