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

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

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

	PR tree-optimization/120582

gcc/ChangeLog:

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