mem-ruby: SLICC-allow expressions in is_valid

Currently, the is_valid statement in slicc requires that there is a
variable passed in as the only parameter. As far as I can tell, there's
no reason not to allow a more flexible expression. If we allow expr
instead of var, then we can eliminate unused variable warnings more
easily.

For instance, the following code won't compile with gem5.fast:
```
TBE tbe := getTBE(...);
assert(is_valid(tbe));
```

However, with this changeset we can fix the problem by using the
following code:
```
assert(is_valid(getTBE(...)));
```
