fix PR symtab/15719
This patch fixes PR symtab/15719.
The bug is that "watch -location" crashes on a certain expression.
The problem is that fetch_subexp_value is catching an exception.
For ordinary watchpoints this is ok; but for location watchpoints,
it is better for the exception to propagate.
Built and regtested on x86-64 Fedora 18.
New test case included.
PR symtab/15719:
* breakpoint.c (update_watchpoint, watchpoint_check)
(watch_command_1): Update.
* eval.c (fetch_subexp_value): Add "preserve_errors"
parameter.
* ppc-linux-nat.c (check_condition): Update.
* value.h (fetch_subexp_value): Update.
* gdb.base/watchpoint.c (struct foo5): New.
(nullptr): New global.
* gdb.base/watchpoint.exp (test_watch_location): Add test.
