4.1.7.6 in ISO 18037 specifies the following type-generic macros for fixed point functions: `absfx`, `roundfx`, `countlsfx`. For each macro, use of the macro invokes the function whose corresponding type and type domain
is the fixed-point type of the first generic argument. If the type of the first generic argument is not a
fixed-point type, the behavior is undefined. All of these functions are already included in llvm libc so we should be good to add these macros.
