These routines should really be done as builtins, as almost all
front ends need this facility and we'd fit in with the common
frameworks for folding etc. The only reason I haven't done this
so far, is that right now there is no general language-indepent
framework for declaring builtins.

Basically, every front end has to set up typed and declarations
for every builtin, which is a bit of a pain, especially since there
are many floating-point formats and integer formats that we
might want to convert between.
