Parameters

Name	Description
DL	Data layout used to size indices and pointers.
Offset	APInt that accumulates the constant byte offset.
AllowNonInbounds	Whether to accumulate non-inbounds GEP offsets.
AllowInvariantGroup	Whether to look through invariant.group intrinsics.
ExternalAnalysis	Optional analysis for non-constant GEP operands.
LookThroughIntToPtr	Whether to look through IntToPtr/PtrToInt.
