Merge pull request #20072 from dlongnecke-cray/internal-error-parenless-method

Fix internal error when calling a parenless method invocation (#20072)

Resolves #19945.

Fix a bug which caused calling the result of a parenless method
invocation to result in an internal error:

writeln(INFINITY());

This code now emits an error:

error: unresolved access of 'real(64)' by '()'

Which is consistent with the errors emitted when trying to call
a type that does not support the call operation.

TESTING

  • ALL on linux64, standard

Reviewed by @mppf. Thanks!
