Implement __builtin_signbitl for PowerPC PowerPC uses the special PPC_FP128 type for long double on Linux, which is composed of two 64-bit doubles. The higher-order double (which contains the overall sign) comes first, and so the __builtin_signbitl implementation requires special handling to extract the sign bit. Fixes PR20691. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@216341 91177308-0d34-0410-b5e6-96231b3b80d8
