Just that it doesn't get forgotten, the attached patch needs to be
applied on top.

It handles 'tile'/'unroll' directive names in the 'contains'/'absent'
clauses of the 'assume'/'assumes' directives.

Currently, we don't do anything with it after parsing; hence, no further
changes are required. (We could add a testcsase, if someone thinks that
it is necessary.)
