Use mark_ssa_maybe_undefs in PHI-OPT

The following removes gimple_uses_undefined_value_p and instead
uses the conservative mark_ssa_maybe_undefs in PHI-OPT, the last
user of the other API.

* tree-ssa-phiopt.cc (pass_phiopt::execute): Mark SSA undefs.
(empty_bb_or_one_feeding_into_p): Check for them.
* tree-ssa.h (gimple_uses_undefined_value_p): Remove.
* tree-ssa.cc (gimple_uses_undefined_value_p): Likewise.
