Current code doesn't support floating point #define macros. This CL compiles floats to a object file and retrive values from it. That approach is the same work as we've already done for integers.

// Test new scheme for deciding whether C.name is an expression, type, constant.

// Clang silences some warnings when the name is a #defined macro, so test those too
