River Riddle 9db53a1827 [mlir][NFC] Remove usernames and google bug numbers from TODO comments.
These were largely leftover from when MLIR was a google project, and don't really follow LLVM guidelines.

Diego Caballero 8a418e5f8e [mlir][Affine] Enable fusion of loops with vector loads/stores
This patch enables affine loop fusion for loops with affine vector loads
and stores. For that, we only had to use affine memory op interfaces in
LoopFusionUtils.cpp and Utils.cpp so that vector loads and stores are
also taken into account.

Rob Suderman e708471395 [mlir][NFC] Cleanup AffineOps directory structure
Summary:
Change AffineOps Dialect structure to better group both IR and Tranforms. This included extracting transforms directly related to AffineOps. Also move AffineOps to Affine.

Rob Suderman 69d757c0e8 Move StandardOps/Ops.h to StandardOps/IR/Ops.h
Summary:
NFC - Moved StandardOps/Ops.h to a StandardOps/IR dir to better match surrounding
directories. This is to match other dialects, and prepare for moving StandardOps
related transforms in out for Transforms and into StandardOps/Transforms.

River Riddle 35807bc4c5 NFC: Introduce new ValuePtr/ValueRef typedefs to simplify the transition to Value being value-typed.
This is an initial step to refactoring the representation of OpResult as proposed in: https://groups.google.com/a/tensorflow.org/g/mlir/c/XXzzKhqqF_0/m/v6bKb08WCgAJ

This change will make it much simpler to incrementally transition all of the existing code to use value-typed semantics.

River Riddle 037742cdf2 Add support for early exit walk methods.
This is done by providing a walk callback that returns a WalkResult. This result is either `advance` or `interrupt`. `advance` means that the walk should continue, whereas `interrupt` signals that the walk should stop immediately. An example is shown below:

auto result = op->walk([](Operation *op) {
  if (some_invariant)
    return WalkResult::interrupt();
  return WalkResult::advance();
});

if (result.wasInterrupted())
  ...;

River Riddle 4bfae66d70 Refactor the 'walk' methods for operations.
This change refactors and cleans up the implementation of the operation walk methods. After this refactoring is that the explicit template parameter for the operation type is no longer needed for the explicit op walks. For example:

    op->walk<AffineForOp>([](AffineForOp op) { ... });

is now accomplished via:

    op->walk([](AffineForOp op) { ... });

Andy Davis 2e1187dd25 Globally change load/store/dma_start/dma_wait operations over to affine.load/store/dma_start/dma_wait.
In most places, this is just a name change (with the exception of affine.dma_start swapping the operand positions of its tag memref and num_elements operands).
Significant code changes occur here:
*) Vectorization: LoopAnalysis.cpp, Vectorize.cpp
*) Affine Transforms: Transforms/Utils/Utils.cpp
