Hi!
In --enable-checking=rtl bootstrap most of SSE/AVX tests fail, because
*mov<mode>_internal is using REGNO on operands that are e.g. MEM or
CONST_INT etc. Fixed thusly, bootstrapped/regtested on x86_64-linux and
i686-linux, committed to trunk as obvious.

* config/i386/sse.md (*mov<mode>_internal): Guard
EXT_REX_SSE_REGNO_P (REGNO ()) uses with REG_P.
