[PATCH 3/5] tree-optimization: Remove dead code in gimple-ssa-nonnull-compare.cc. [PR120580]

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/120580

gcc/ChangeLog:

	* gimple-ssa-nonnull-compare.cc (do_warn_nonnull_compare):
	Remove dead code.
