[PATCH 5/5] ssa-dce: use safe_emplace_push

[Andrew Pinski]

This is small cleanup now vec has safe_emplace_push. We can just call
safe_emplace_push instead of also causing make_pair.

Bootstrapped and tested on x86_64-linux-gnu.

gcc/ChangeLog:

        * tree-ssa-dce.cc (make_forwarders_with_degenerate_phis): Use 
safe_emplace_push
        instead of `safe_push( std::make_pair (`.
