[PATCH 4/5] ssa-forwprop: 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-forwprop.cc (simplify_gimple_switch_label_vec): Use 
safe_emplace_push
        instead of `safe_push( std::make_pair (`.
        (simplify_vector_constructor): Likewise.
