[Reland][LSR] Hoist IVInc to loop header if its all uses are in the loop header
Original code will cause crash when the load/store memory type is structure because isIndexedLoadLegal/isIndexedStore doesn't support struct type.
So we limit the load/store memory type to integer.
Origin commit message:
When the latch block is different from header block, IVInc will be expanded in the latch loop. We can't generate the post index load/store this case.
But if the IVInc only used in the loop, actually we still can use the post index load/store because when exit loop we don't care the last IVInc value.
So, trying to hoist IVInc to help backend to generate more post index load/store.
Fix #53625
