rtl-ssa: Avoid creating duplicated phis

If make_uses_available was called twice for the same use,
we could end up trying to create duplicate definitions for
the same extended live range.

gcc/
* rtl-ssa/blocks.cc (function_info::create_degenerate_phi): Check
whether the requested phi already exists.
