commit fec0d69f8a1ceae68a17f69ada797686369f5536

Clean up agtype_to_int8, agtype_to_int4, & agtype_to_int2 (#1354)
Cleaned up the code in `agtype_to_int8`, `agtype_to_int4`, and
`agtype_to_int2`. There was some dead code after implementing
PR 1339.
Additionally, modified the error messages to be a bit more helpful
and modified the logic to cover a few more cases.
Added more regression tests.
