51525 5962 d 18 h falcon /trunk/ Use address-based hash for cached non-UTF8 in match, match4  
51524 5962 d 18 h falcon /trunk/src/main/ Add missing initialization for new HashData.useCache field  
51483 5964 d 16 h falcon /trunk/ unique(): compare CHARSXP by address if ASCII and cached

If all CHARSXPs in a given STRSXP have unmarked encoding (ASCII) and are
in the CHARSXP cache, then we compute a hash value based on the address.
Otherwise, the string data is translated to UTF8 and walked to compute
the hash value. This provides a speed-up for the ASCII + cached case.
