Accept missing semicolon after do-while statement.

Although not valid according to ECMA 5.1, both JSC and V8 accept a
missing semicolon after a do-while loop. (Both JSC and V8 do not do this
through automatic semicolon insertion, but handle it as a special case.)

This is a "port" of a similair change done in the qtdeclarative module.
