Finish support for 64-bit types in stdlib. Fixes issue #14.

Browse Source 
Add much more suppport for doubles and in64 types in the standard library, basically supporting everything for them that are supported for floats and int32s.  (The notable exceptions being the approximate rcp() and rsqrt() functions, which don't really have sensible analogs for doubles (or at least not built-in instructions).)
