[PULL 06/12] tests/fp: split and audit the conversion tests

[Alex Bennée]

Split the float conversion tests into separate groups and audit the
tests to check what is still broken. I was able to enable a bunch of
tests that had been missed before:

  all the float to float conversions
  ui32_to_extF80
  ui64_to_extF80
  extF80_to_ui32
  extF80_to_ui32_r_minMag
  extF80_to_ui64
  extF80_to_ui64_r_minMag
