Add the collective subroutine, `co_reduce`, to the list of 
intrinsic subroutines. Move the check in `ApplySpecificChecks()`
for the intrinsic function, `reduce`, to a new function that can
perform the same checks on `co_reduce` as well. Add to the new
function, `CheckReduceAndCoReduce`, the additional checks that
only apply for the `operation` argument for `co_reduce`. Also
change the check for the `volatile` attribute on the `operation`
argument for `reduce` and `co_reduce` to a check for the `value`
attribute, since that is the attribute that is disallowed by the
standard. Update the `co_reduce` and `reduce` semantics tests.
