8033545: Missing volatile specifier in Bitmap::par_put_range_within_word Summary: The method Bitmap::par_put_range_within_word reloads the original value during a CAS, which may be optimized away. Instead of reloading, use the value returned by Atomic::cmpxchg_ptr() for further processing. Reviewed-by: tschatzl, brutisso, tonyp Contributed-by: Matthias Braun <matthia.braun@sap.com>
