gccrs: destructure parameter names.

When we have complex generic code you can end up with situations where we
compile types:

  Maybe<<S as Foo>::A>

Into

  Maybe<<placeholder:<Projection=::()>>>

This calls destructure to cleanup the naming here and avoid making non
canonical TREE_TYPES hitting the verify_gimple code triggering non-trival
constructors.
