psi2ir: don't generate temporaries in dynamic array augmented assignment

Browse Source 
In constructs such as 'd[i] += x', where both indexed get and indexed
set are dynamic calls, it's safe to generate augmented assignment body
directly, without temporary variables for array ('d') and index ('i').
Note that corresponding IntermediateValue's are OnceExpressionValue's,
which would throw an exception if this assumption is violated.
