[llvm-dev] RFC: Constant folding math functions for long double

Hey James,

I really fundamentally dislike libMPFR.

License of the codebase aside, would a dependency be on the built .so, 
or would it be that we'd want to pull in the code and build that?

My worry if we do bring it in even as a soft dependency is how is this 
figured out - is it a case that CMake will, if it finds the .so on the 
system, use and link against it? I worry that we are introducing another 
matrix of potential failures if the lib is present or not.
