Hi,

Aarch64: watchpoints set on non-8-byte-aligned addresses are always missed
https://sourceware.org/bugzilla/show_bug.cgi?id=19806

some unaligned watchpoints are currently missed.  After this patch some other
unaligned watchpoints will get reported as false positives.

It could be probably all fixed on the kernel side, filed a RFE for it:
	kernel RFE: aarch64: ptrace: BAS: Support any contiguous range
	https://sourceware.org/bugzilla/show_bug.cgi?id=20207
->
	https://bugzilla.redhat.com/show_bug.cgi?id=1342821
I have no idea if/when the kernel part gets fixed so I am posting this
hopefully-temporary GDB change.

No regressions on aarch64-fedora23-linux-gnu in native mode.
No regressions on {x86_64,x86_64-m32,i686}-fedorarawhide-linux-gnu in native
and gdbserver mode.
