Javed Absar 382f98733a [ConstantFold] Fix defect in constant folding computation for GEP ... When the array indexes are all determined by GVN to be constants, a call is made to constant-folding to optimize/simplify the address computation. The constant-folding, however, makes a mistake in that it sometimes reads back stale Idxs instead of NewIdxs, that it re-computed in previous iteration. This leads to incorrect addresses coming out of constant-folding to GEP. A test case is included. The error is only triggered when indexes have particular patterns that the stale/new index updates interplay matters.
