[PATCH] Fix simplify_const_unary_operation sNaN handling (PR tree-optimization/61441)

Hi! As I wrote earlier today on gcc-patches, pr61441.c started failing on i?86-linux when -fsignaling-nans argument has been added to it. I believe this is because the simplify_const_unary_operation changes in r231901 were broken, when the operand is a sNaN and -fsignaling-nans, we want to avoid
