Cody Tapscott b5d5685a4e compiler_rt: Implement floatXiYf/fixXfYi, incl f80 
This change:
 - Adds  generic implementation of the float -> integer conversion
   functions floatXiYf, including support for f80
 - Updates the existing implementation of integer -> float conversion
   fixXiYf to support f16 and f80
 - Fixes the handling of the explicit integer bit in `__trunctfxf2`
 - Combines the test cases for fixXfYi/floatXiYf into a single file
 - Renames `fmodl` to `fmodq`, since it operates on 128-bit floats

The new implementation for floatXiYf has been benchmarked, and generally
provides equal or better performance versus the current implementations:
