Hi,

Please review the change for JDK-8071962, "The SA code needs to be updated to 
support Symbol lookup from the shared archiveā€.

In JDK-8059510, we introduced a compact form of hash table for the symbols in 
shared archive. The shared symbols are stored separately from the regular 
symbol table. The VM looks up both tables when searching for existing symbol at 
runtime. The SA code needs to do the same when looking up symbols.

Webrev: http://cr.openjdk.java.net/~jiangli/8067977/webrev.00/

Tested on both 32-bit and 64-bit platforms:
  bin/java sun.jvm.hotspot.tools.DumpJFR <pid>

JPRT tests in progress.

Thanks,
Jiangli
