accessedOffsetInRangeCTimesLid and accessedOffsetInRangeCTimesGid invariant generation rules never trigger

[jeroenk]

This is due to commit 68bc077, which causes GPUVerify to generate statements like assume v0 and assume !v0 instead of assume v0 && v0 and assume !v0 && !v0. This breaks the logic of GetILessThanC, which depends on && occurring at the root of the expression.

We should investigate whether the rules can simply be removed, because they have been superseded by access breaking, or whether we can make them less fragile.
