[svn r330] Implemented synchronized statements. Changed the tryfinally handlers to a more generalized EnclosingHandler. Changed ClassInfoS to be mutable so they can be used as locks. Added new BB after throw ala return/break etc.

module globals2;

template Bool(bool b)
{
    const bool Bool = b;
}

void main()
{
    assert(Bool!(true));
    assert(!Bool!(false));
}
