Hi,

The trilogy of patches now has a fourth part - watchpoint function
changes. These had to be written since Jan pointed out that s390x allows
arbitrary length watchpoints using a range. In fact, there are some
other architectures that seem to do this too.

The patch does not cause any regressions in the testsuite. It
introduces some new warnings in splint, but I found them to be safe,
since the watchpoint sizes in those cases would be bound to within
sizeof (int). E.g. i386 watchpoints.
