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.
