[PATCH 5/5] tree-optimization: Remove dead code in tree-ssa-forwprop.cc. [PR120582]

[Kael Andrew Alonzo Franco]

This is dead since COND_EXPR is always a SSA_NAME or a constant.

Bootstrapped and regtested on x86_64-pc-linux-gnu.

gcc/ChangeLog:

        * tree-ssa-forwprop.cc (simplify_builtin_call): Remove dead code.
