This IR code
%res = call <8 x float> @llvm.x86.avx.cmp.ps.256(<8 x float> %a0, <8 x float> %a1, i8 14)
fails with assertion:

llc: X86ATTInstPrinter.cpp:62: void llvm::X86ATTInstPrinter::printSSECC(const llvm::MCInst*, unsigned int, llvm::raw_ostream&): Assertion `0 && "Invalid ssecc argument!"' failed.
0  llc             0x0000000001355803

Attached a fix. Please review.
