Add builtin for performing checked conversion between integer types. (#4523)

As a prerequisite for switching the type of int literals to be the
`IntLiteral` type, add support for performing conversions of in-bounds
integer constant values to other integer types in which they fit.

This incidentally is our first compile-time-only builtin function, so
add very minimal support for compile-time-only functions while we're
here.
