River Riddle d2f3e5f204 [mlir] Add support for non-identifier attribute names.
Summary: In some situations the name of the attribute is not representable as a bare-identifier, this revision adds support for those cases by formatting the name as a string instead. This has the added benefit of removing the identifier regex from the verifier.

Mehdi Amini 308571074c Mass update the MLIR license header to mention "Part of the LLVM project"
This is an artifact from merging MLIR into LLVM, the file headers are
now aligned with the rest of the project.

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 e7d594bb1c Replace the implementation of Function and Module with FuncOp and ModuleOp.
This is an important step in allowing for the top-level of the IR to be extensible. FuncOp and ModuleOp contain all of the necessary functionality, while using the existing operation infrastructure. As an interim step, many of the usages of Function and Module, including the name, will remain the same. In the future, many of these will be relaxed to allow for many different types of top-level operations to co-exist.

River Riddle d3f743252d NFC: Move the Function/Module/Operation::verify methods out-of-line.
As Functions/Modules becomes operations, these methods will conflict with the 'verify' hook already on derived operation types.

River Riddle 54cd6a7e97 NFC: Refactor Function to be value typed.
Move the data members out of Function and into a new impl storage class 'FunctionStorage'. This allows for Function to become value typed, which will greatly simplify the transition of Function to FuncOp(given that FuncOp is also value typed).

River Riddle 8c47e2ed5c Extract the automatic function renaming and symbol table out of Module.
This functionality is now moved to a new class, ModuleManager. This class allows for inserting functions into a module, and will auto-rename them on insert to ensure a unique name. This now means that users adding new functions to a module must ensure that the function name is unique, as the Module will no longer do it automatically. This also means that Module::getNamedFunction now operates in O(N) instead of the O(c) time it did before. This simplifies the move of Modules to Operations as the ModuleOp will not be able to have this functionality.

River Riddle a4c3a6455c Move the emitError/Warning/Remark utility methods out of MLIRContext and into the mlir namespace.
Now that Locations are attributes, they have direct access to the MLIR context. This allows for simplifying error emission by removing unnecessary context lookups.

River Riddle c33862b0ed Refactor FunctionAttr to hold the internal function reference by name instead of pointer. The one downside to this is that the function reference held by a FunctionAttr needs to be explicitly looked up from the parent module. This provides several benefits though:
* There is no longer a need to explicitly remap function attrs.
      - This removes a potentially expensive call from the destructor of Function.
      - This will enable some interprocedural transformations to now run intraprocedurally.
      - This wasn't scalable and forces dialect defined attributes to override
        a virtual function.
    * Replacing a function is now a trivial operation.
    * This is a necessary first step to representing functions as operations.

River Riddle baa656352a Add the ability to attach notes to Diagnostic/InFlightDiagnostic.
Notes are a way to add additional context to a diagnostic, but don't really make sense as standalone diagnostics. Moving forward, notes will no longer be able to be constructed directly and must be attached to a parent Diagnostic.

    Notes can be attached via `attachNote`:

      auto diag = ...;
      diag.attachNote() << "This is a note";

River Riddle 082016d43a Add a flag to Dialect that allows for dialects to enable support for unregistered operations. This flag is off by default and can be toggled via the 'allowUnknownOperations(...)' method. This means that moving forward an error will be emitted for unknown operations if the dialect does not explicitly allow it.
Example:

    func @unknown_std_op() {
      %0 = "std.foo_bar_op"() : () -> index
      return
    }

    Will result in:

    error: unregistered operation 'std.foo_bar_op' found in dialect ('std') that does not allow unknown operations

Alex Zinenko 5a5bba0279 Introduce affine terminator
Due to legacy reasons (ML/CFG function separation), regions in affine control
flow operations require contained blocks not to have terminators.  This is
inconsistent with the notion of the block and may complicate code motion
between regions of affine control operations and other regions.

Introduce `affine.terminator`, a special terminator operation that must be used
to terminate blocks inside affine operations and transfers the control back to
he region enclosing the affine operation.  For brevity and readability reasons,
allow `affine.for` and `affine.if` to omit the `affine.terminator` in their
regions when using custom printing and parsing format.  The custom parser
injects the `affine.terminator` if it is missing so as to always have it
present in constructed operations.

Update transformations to account for the presence of terminator.  In
particular, most code motion transformation between loops should leave the
terminator in place, and code motion between loops and non-affine blocks should
drop the terminator.
