This patch adds the tree-ssa-ifcombine.h header file, with the function
declarations for `recognize_if_then_else` and `same_phi_args_p` 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 (recognize_if_then_else): Removed 'static'
and default value for 'succs_any'.
(same_phi_args_p): Removed 'static'.
* tree-ssa-ifcombine.h: New file.
