re PR tree-optimization/24300 (segfault in operand_equal_p with -ftree-vectorize)
PR tree-opt/24300
* Makefile.in (tree-ssa-dce.o): Depend on CFGLOOP_H.
* tree-ssa-dce.c: Include cfgloop.h.
(tree_ssa_dce_loop, pass_dce_loop): New.
* tree-pass.h (pass_dce_loop): Declare it.
* passes.c (init_optimization_passes): Use it.
