add support for quadruple precision floating point
This currently requires linking against a library like libquadmath (or libgcc), because compiler-rt barely has any support for this and most hardware does not yet have 128-bit precision floating point. For this reason, it's currently hidden behind a feature gate. When compiler-rt is updated to trunk, some tests can be added for constant evaluation since there will be support for the comparison operators. Closes #13381
