[Bug breakpoints/10679] New: replay mode should set can-use-hw-watchpoints 0

["jan dot kratochvil at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

gdb -nx -ex 'set confirm no' -ex start -ex record -ex c -ex reverse-continue -ex
'watch j' -ex c ./loopsimple
GNU gdb (GDB) 7.0.50.20090921-cvs
[...]
No more reverse-execution history.
main () at loopsimple.c:6
6	  for (i = 0; i < 1000; i++)
Hardware watchpoint 2: j

Watchpoint 2 deleted because the program has left the block in
which its expression is valid.
__libc_start_main (main=<value optimized out>, argc=<value optimized out>,
ubp_av=<value optimized out>, init=<value optimized out>, 
    fini=<value optimized out>, rtld_fini=<value optimized out>,
stack_end=0x7fffffffd5a8) at libc-start.c:252
252	  exit (result);
(gdb) _

But this way it works:

gdb -nx -ex 'set confirm no' -ex start -ex record -ex c -ex reverse-continue -ex
'set can-use-hw-watchpoints 0' -ex 'watch j' -ex c ./loopsimple
GNU gdb (GDB) 7.0.50.20090921-cvs
[...]
No more reverse-execution history.
main () at loopsimple.c:6
6	  for (i = 0; i < 1000; i++)
Watchpoint 2: j
Watchpoint 2: j

Old value = 0
New value = 1
main () at loopsimple.c:6
6	  for (i = 0; i < 1000; i++)
(gdb) 

------------------------------------------------------------------------------

int
main (void)
{
  int i, j;

  for (i = 0; i < 1000; i++)
    j = i;

  return 0;
}
