[PATCH] Expand __builtin_memcmp_eq with ptest for OI/TImode.

Enable optimization for TImode only under 32-bit target, for 64-bit target there could be extra ineteger <-> sse move regarding psABI, not efficient. Bootstrapped and regtested on x86_64-pc-linux-gnu{-m32,} Ok for trunk? gcc/ChangeLog: PR target/104610 * config/i386/i386-expand.c
