Bug #11760361 52764: EXTEND MYSQL-TEST-RUN SUPPORT FOR SUN STUDIO DBX BY ADDING --DBX DEBUGGER

Added necessary options and variables
Added dbx_arguments() similar to gdb_arguments()
Unlike gdb, cannot use init file but must provide commands and args as
  command line argument to dbx
Also simplified debugger behavior to always start with a breakpoint in main()
