Simplification of non-equality predicates for solving constraint
systems is now supported by checking the validity of related
inequalities and equalities.

Simplification of equality predicates is now supported by
transferring equalities into inequalities. This is achieved
by separately checking that both `isConditionImplied(A >= B)`
and `isConditionImplied(A <= B)` hold.

Use collectOffset to collect scaled indices and constant offset for GEP
instead of custom code. This simplifies the logic in decomposeGEP and
allows to handle all cases supported by the generic helper.
