This patch adds the tree-ssa-ifcombine.h header file, with the function
declarations for `recognize_if_then_else` and `tree_ssa_ifcombine_bb` and
removes 'static' from the definitions in tree-ssa-ifcombine.cc, so that they
can be used in other passes.
gcc/ChangeLog:
* tree-ssa-ifcombine.cc: Include tree-ssa-ifcombine.h.
(recognize_if_then_else): Removed 'static'.
(tree_ssa_ifcombine_bb): Removed 'static'.
* tree-ssa-ifcombine.h: New file.
