Log:
        PR c++/88183 - ICE with .* fold-expression.

build_m_component_ref can't handle type-dependent operands, so let's use the
default case; tsubst_copy_and_build also uses build_x_binary_op for
substituting a DOTSTAR_EXPR.

        * pt.c (fold_expression) [DOTSTAR_EXPR]: Remove special handling.
