go/types: use an identifier map rather than isubst for recv type params Receiver type parameters are the only type expressions allowed to be blank. Previously this was handled by substitution of synthetic non-blank names in the receiver type expression, but that introduced problems related to AST mangling: the scope had extra elements, Object.Name() was inaccurate, and synthetic nodes were recorded in types.Info. Fix this instead by recording a map of *ast.Ident->*TypeParam on the Checker, which is read in Checker.ident to resolve blank identifiers denoting receiver type parameters.
