Clear non-significant bits of address in watchpoint

Nowadays, GDB can't set watchpoint on tagged address on AArch64,

(gdb) p p2
$1 = (int *) 0xf000fffffffff474
(gdb) watch *((int *) 0xf000fffffffff474)
Hardware watchpoint 2: *((int *) 0xf000fffffffff474)
(gdb) c
Continuing.
main () at
binutils-gdb/gdb/testsuite/gdb.arch/aarch64-tagged-pointer.c:45
45	  void (*func_ptr) (void) = foo;
Unexpected error setting hardware debug registers

This patch is about setting watchpoint on a tagged address.  Unlike
breakpoint, watchpoint record the expression rather than the address, and
when a watchpoint is fired, GDB checks the expression value changed
instead of matching address, so we can mask the watchpoint address by
getting rid of non-significant bits of address.

gdb:

2017-12-08  Yao Qi  <yao.qi@linaro.org>

	* breakpoint.c (update_watchpoint): Call
	address_significant.

gdb/testsuite:

2017-12-08  Yao Qi  <yao.qi@linaro.org>

	* gdb.arch/aarch64-tagged-pointer.c (main): Update.
	* gdb.arch/aarch64-tagged-pointer.exp: Add tests for watchpoint.
