[regexp] Update semantics of GetSubstitution with named captures 

The specced semantics of GetSubstitution are expected to change in the
case of malformed named references, or named references to nonexistent
named groups. The former will evaluate to the identity replacement of
'$<', while the latter will result in replacement by the empty string.
