Subject: When transforming a C++ "new" expression's constructor arguments,
 drop any arguments that are default-argument expressions. The can show up
 when we have a new expression whose constructor arguments are not
 type-dependent and whose allocated type is not dependent and has a
 constructor with default arguments. Fixes PR7202.
