Peiyong Lin 04ad8d4900 Emit inbounds and nuw attributes in memref. (#138984) ...

Now that MLIR accepts nuw and nusw in getelementptr, this patch emits
the inbounds and nuw attributes when lower memref to LLVM in load and
store operators.

This patch also strengthens the memref.load and memref.store spec about
undefined behaviour during lowering.

This patch also lifts the |rewriter| parameter in getStridedElementPtr
ahead so that LLVM::GEPNoWrapFlags can be added at the end with a
default value and grouped together with other operators' parameters.
