Move brackets enclosing declarator in a couple of V8_DEPRECATE_SOON
cases so that the attribute is correctly placed.

I.e. should come after the class keyword and after a function signature
but before the body.

Also adds suppressions for a case where a replacement method calls
the deprecated method it replaces.
