Member predicate GuardedExpr :: getAGuard

Gets an expression that guards this expression. That is, this expression is only reached when the returned expression has abstract value v.

The expression sub is a sub expression of the guarding expression that is structurally equal to this expression.

In case this expression or sub accesses an SSA variable in its left-most qualifier, then so must the other (accessing the same SSA variable).
