Fix use of SSE1 registers for f32 ops in no-x87 mode. Notably, allow use of SSE instructions for f32 operations in 64-bit mode (but not 32-bit which is disallowed by callign convention). Also avoid translating memset/memcopy/memmove into SSE registers without X87 for 32-bit mode. This fixes PR38738.
