Herald added a project: LLVM.

This patch introduces interfaces for read and write ops with affine
restrictions. I used `read`/`write` intead of `load`/`store` for the
interfaces so that they can also be implemented by dma ops.
For now, they are only implemented by affine.load, affine.store,
affine.vector_load and affine.vector_store.

For testing purposes, this patch also changes affine loop fusion and
required analysis to use the new interfaces. I can create a separate patch
for this, if needed, but I think it's good to have this initial
version for context.
