Hi!

I hope this pattern actually shouldn't be used for AVX512*, because
vpinsr should match instead, but just in case it doesn't, all the insns
involved are in AVX512F.

Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?

	* config/i386/sse.md (sse2_loadld): Use v instead of x
	constraint in alternatives 0,1,4.
