closes #3582: typedTypeDef needs to run in a new typer for TypeDefs with
type parameters
this was honored when typedTypeDef was called by typed1, but other
callers did not this would cause higher-order type parameters to be
re-entered in the scope of a method or a class
(by the way, should we recycle scopes for higher-order type params? now
new scopes are created, symbols entered, and tree's symbols updated)
changed some spurious vars to vals
