They're essentially type casts;  they take IEEE format
bit patterns (single or double) and convert to Limbo real.

These were tossed in at the last minute and undocumented
because I knew they weren't in final form.  Probably we'll
go with functions mapping an array of (big-endian) bytes
to and from an array of real.
