    testsuite: Fix up new51.C test on various targets [PR108533]
    
    The test fails on targets where size_t is not unsigned long
    due to extra diagnostics.
    
    As the testcase is tested in C++98 too, I'm not using decltype (sizeof 0)
    but __SIZE_TYPE__.

            * g++.dg/init/new51.C (size_t): New typedef.
            (RexxClass::operator new, RexxClass::operator delete): Use size_t
            instead of unsigned long.
