Add APInt interfaces to APFloat (allows directly
...
access to bits). Use them in place of float and
double interfaces where appropriate.
First bits of x86 long double constants handling
(untested, probably does not work).

Fix mod so it actually works. Fix conversions to
...
native types to handle denormals correctly.

...
This means backing out the preceding change to Constants.cpp, alas.
