Match the builtins that GCC provides for IEEE754 quad precision on MIPS64. Also, enable building them with clang as PR20098 is resolved. Disable tests for xf and xc modes as MIPS doesn't support that mode in hardware or software. Reviewers: slthakur Differential Revision: https://reviews.llvm.org/D32794 llvm-svn: 302147
