[PATCH, i386]: Fix PR72867, incorrect optimization of VMINPS/VMAXPS at compile time

Hello! Attached patch applies min/max IEEE rules w.r.t. NaN and signed zeros also to SSE intrinsics. Before the patch, intrinsics were expanded to a generic min/max pattern with commutative operands. Patched compiler expands intrinsics to an UNSPEC or generic min/max, depending on
