```
compiler_rt: Fix rounding/NaN handling for f80 add/sub

There were a few minor bugs in the rounding behavior and Inf/NaN
handling for the f80 __addxf3 and __subtf3 functions.

This change updates the original generic implementation to correctly
handle f80 floats, including the explicit integer bit.

```
