DirectPropertyGet is a statically bound instance access used in the
VM mixin tranformation to encode fully resolved super access. The
access to `this.name` generated in `toString` of an enum is _not_
a statically bound instance access but just a regular instance access
whose runtime target happens to be known statically because the code
is generated. In JavaScript backend a statically bound instance access
requires a unique getter to avoid the dynamic lookup, and therefore,
though using DirectPropertyGet is an optimization
to the VM, it would be a regression to the JavaScript backends if
they didn't handle DirectPropertyGet as a PropertyGet.
This CL removes the misuse and thus enables JavaScript backends to
handle DirectPropertyGet with the intended semantics.
