This patch fixes some bugs in handling of assumed-rank arguments 
revealed by the TS29113 testsuite, allowing xfails to be removed from 
those testcases.  It was previously failing to diagnose an error when 
passing an assumed-rank argument to a procedure via a non-assumed-rank 
dummy, and giving a bogus error when passing one as the first argument 
to the ASSOCIATED intrinsic.  Both fixes turned out to be 1-liners.  OK 
to commit?
