[RISCV] Adjust RV64I data layout by using n32:64 in layout string
Although i32 type is illegal in the backend, RV64I has pretty good support for i32 types by using W instructions.
By adding n32 to the DataLayout string, middle end optimizations will consider i32 to be a native type. One known effect of this is enabling LoopStrengthReduce on loops with i32 induction variables. This can be beneficial because C/C++ code often has loops with i32 induction variables due to the use of `int` or `unsigned int`.
If this patch exposes performance issues, those are better addressed by tuning LSR or other passes.

[RISCV] Return false from isOffsetFoldingLegal instead of reversing the fold in lowering.
When lowering GlobalAddressNodes, we were removing a non-zero offset and
creating a separate ADD.
It already comes out of SelectionDAGBuilder with a separate ADD. The
ADD was being removed by DAGCombiner.
This patch disables the DAG combine so we don't have to reverse it.
Test changes all look to be instruction order changes. Probably due
to different DAG node ordering.
