Uday Bondhugula dfc752e42b Generate strided DMAs from -dma-generate ...

- generate DMAs correctly now using strided DMAs where needed
- add support for multi-level/nested strides; op still supports one level of
  stride for now.

Other things
- add test case for  symbolic lower/upper bound; cases where the DMA buffer
  size can't be bounded by a known constant
- add test case for dynamic shapes where the DMA buffers are however bounded by
  constants
- refactor some of the '-dma-generate' code
