You may need to add 2 new SSE register classs, one for xmm0 and one
for other xmmN, like Y0 and Yn I added in my original SSE4.1 patch:

Otherwise, you will run into

For now, I have reverted blendv part of my previous patch so there is no failure anymore. I wonder how I missed this during testing, perhaps a good sleep is needed from time to time. ;]

Sorry for this glitch.

* config/i386/i386.c (ix86_expand_sse_4_operands_builtin): Call
safe_vector_operand() if input operand is VECTOR_MODE_P operand.
(ix86_expand_sse_pcmpestr): Do not check operands for
"register_operand", when insn operand predicate is "register_operand".
(ix86_expand_sse_pcmpistr): Ditto.

Uros.
