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.

Tim Shen 3ccaac3cdd [mlir] Add MemRefTypeBuilder and refactor some MemRefType::get().
The refactored MemRefType::get() calls all intend to clone from another
memref type, with some modifications. In fact, some calls dropped memory space
during the cloning. Migrate them to the cloning API so that nothing gets
dropped if they are not explicitly listed.

It's close to NFC but not quite, as it helps with propagating memory spaces in
some places.

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 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) { ... });

Uday Bondhugula aa2cee9cf5 Refactor / improve replaceAllMemRefUsesWith
Refactor replaceAllMemRefUsesWith to split it into two methods: the new
method does the replacement on a single op, and is used by the existing
one.

- make the methods return LogicalResult instead of bool

- Earlier, when replacement failed (due to non-deferencing uses of the
  memref), the set of ops that had already been processed would have
  been replaced leaving the IR in an inconsistent state. Now, a
  pass is made over all ops to first check for non-deferencing
  uses, and then replacement is performed. No test cases were affected
  because all clients of this method were first checking for
  non-deferencing uses before calling this method (for other reasons).
  This isn't true for a use case in another upcoming PR (scalar
  replacement); clients can now bail out with consistent IR on failure
  of replaceAllMemRefUsesWith. Add test case.

- multiple deferencing uses of the same memref in a single op is
  possible (we have no such use cases/scenarios), and this has always
  remained unsupported. Add an assertion for this.

- minor fix to another test pipeline-data-transfer case.

Mehdi Amini 926fb685de Express ownership transfer in PassManager API through std::unique_ptr (NFC)
Since raw pointers are always passed around for IR construct without
implying any ownership transfer, it can be error prone to have implicit
ownership transferred the same way.
For example this code can seem harmless:

  Pass *pass = ....
  pm.addPass(pass);
  pm.addPass(pass);
  pm.run(module);

Nicolas Vasilache 258e8d9ce2 Prepend an "affine-" prefix to Affine pass option names - NFC
Trying to activate both LLVM and MLIR passes in mlir-cpu-runner showed name collisions when registering pass names.
    One possible way of disambiguating that should also work across dialects is to prepend the dialect name to the passes that specifically operate on that dialect.

    With this CL, mlir-cpu-runner tests still run when both LLVM and MLIR passes are registered
