Richard Smith 246ec785df Add support for converting between integer types (#4753) 
Add a builtin `"int.convert"` supporting unchecked conversions between
different integer types. This performs a truncation, zero-extension, or
sign-extension, depending on the widths of the operands and the
signedness of the source type. Add explicit `As` support to the prelude.
No implicit conversions are supported yet as we don't have a way to
express the constraint that we can only implicitly convert to wider
types.
