Some optimization for speed.

o Take an array argument where the results are stored instead of
  returning two values.
o Declare speed 3 to get compiler notes and better optimization
o Add missing declarations to reduce number of compiler notes. More
  work needed.
Initial optimization

o Declare speed 3
o Add some more declarations to squash some compiler notes.  More work
  needed.

Put code in IEEE754 package.
Define regression tests using RT.
