    Add regression test for PR gdb/19858 (JIT code registration on attach)

    This test would fail without the previous gdb/jit.c fix:

      (gdb) attach 23031
      Attaching to program:
.../build/gdb/testsuite/outputs/gdb.base/jit/jit-main, process 23031
      [...]
      207           WAIT_FOR_GDB; i = 0;  /* gdb break here 1 */
      (gdb) PASS: gdb.base/jit.exp: attach: one_jit_test-2: attach
      set var wait_for_gdb = 0
      (gdb) PASS: gdb.base/jit.exp: attach: one_jit_test-2: set var
wait_for_gdb = 0
      info function ^jit_function
      All functions matching regular expression "^jit_function":
      (gdb) FAIL: gdb.base/jit.exp: attach: one_jit_test-2: info function
^jit_function

        PR gdb/19858
        * gdb.base/jit-main.c: Include unistd.h.
        (ATTACH): Define to 0 if not already defined.
        (wait_for_gdb, mypid): New globals.
        (WAIT_FOR_GDB): New macro.
        (MAIN): Set an alarm.  Store the process's pid.  Wait for GDB at
        some breakpoint locations.
        * gdb.base/jit.exp (clean_reattach, continue_to_test_location):
        New procedures.
        (one_jit_test): Add REATTACH parameter, and handle it.  Use
        continue_to_test_location.
        (top level): Test attach, and adjusts calls to one_jit_test.
