fpu/softfloat: re-factor sqrt (2018-02-21 10:21:54 +0000)
----------------------------------------------------------------
This is the re-factor of softfloat:
- shared common code path float16/32/64
- well commented and easy to follow code
- added a bunch of float16 support
While some operations are slower the key ones exercised by the
floating point dbt-bench are the same: https://i.imgur.com/oXNJNql.png
