Revert "Added the `name' symbol"

This reverts commit 7383631c0974783861f1a929426052fd2f636e78.

I do not see any reason for exporting the symbol 'name' from designators. It is
not used as slot, class or method name anywhere and exporting it might lead to
a bunch of shadowing problems.
Added predicate to check for new type of manipulation designator: constraint-designators.
