Thanks, Craig! 

I built llvm-mc from r138250, and it looks like the vandpd/vandnpd cases are
fixed, but I still see problems with vandps/vandnps:

$ echo '0xc5 0xf1 0x54 0x3a'| ./llvm-mc -disassemble -triple="x86_64"
        vandpd  (%rdx), %xmm1, %xmm7

$ echo '0xc5 0xf1 0x55 0x3a'| ./llvm-mc -disassemble -triple="x86_64"
        vandnpd (%rdx), %xmm1, %xmm7

$ echo '0xc5 0xf0 0x54 0x3a'| ./llvm-mc -disassemble -triple="x86_64"
        andps   (%rdx), %xmm7

$ echo '0xc5 0xf0 0x55 0x3a'| ./llvm-mc -disassemble -triple="x86_64"
        andnps  (%rdx), %xmm7
