6987812: 2/3 SAJDI: "gHotSpotVMTypes was not initialized properly in the remote process"
Summary: Change ExportDirectoryTableImpl to return the 'Export RVA' field without modification. Read 'Base Of Data' field in optional header when PE32 format COFF file is read. Refine search for dbgeng.dll and dbghelp.dll. Other cleanups.
