Hao Liu 1d2a061bd8 [SeparateConstOffsetFromGEP] Allow SeparateConstOffsetFromGEP pass to lower GEPs. ...

If LowerGEP is enabled, it can lower a GEP with multiple indices into GEPs with a single index
or arithmetic operations. Lowering GEPs can always extract structure indices. Lowering GEPs can
also give use more optimization opportunities. It can benefit passes like CSE, LICM and CGP.
