properties:
- They allow type checked dynamic casting from their base Operation.
- They allow nice accessors for C++ clients, e.g. a "getIndex()" method on
'dim' that returns an unsigned.
- They work with both OperationInst/OperationStmt (once OperationStmt is
implemented).
- They get custom printing logic. They will eventually get custom parsing,
verifier, and builder logic as well.
- Out of tree clients can register their own operation set without having to
change MLIR core, e.g. for TensorFlow or custom target instructions.
This registers addf and dim as examples.

A recursive descent parser for affine maps/expressions with operator precedence and
associativity. (While on this, sketch out uniqui'ing functionality for affine maps
and affine binary op expressions (partly).)

Add a default error reporter for the parser that uses the SourceManager to print the error. Also and OptResult enum (mirroring ParseResult) to make the behavior self-documenting.

important for low-bitwidth inference cases and hardware synthesis targets.
Rename 'int' to 'affineint' to avoid confusion between "the integers" and "the int
type".

Introduce an Identifier class to MLIRContext to represent uniqued identifiers,
introduce string literal support to the lexer, introducing parser and printer
support etc.

- place-holder classes for AffineMap
- module contains a list of affine maps (defined at the top level).

For checking parse errors, the input file is split and failures reported per memory buffer. Simply reporting the errors loses the mapping back to the original file. Change the reporting to instead relate the error reported back to the original file.
Use SourceMgr's PrintMessage consistently for errors and relates back to file being parsed.

Add diagnostic reporter function to lexer/parser and use that from mlir-opt to report errors instead of having the lexer/parser print the errors.

Add parsing tests with errors. Follows direct path of splitting file into test groups (using a marker) and parsing each section individually. The expected errors are checked using FileCheck and parser error does not result in terminating parsing the rest of the file if check-parser-error.
This is an interim approach until refactoring lexer/parser.

This is pretty much minimal scaffolding for this step. Basic block arguments,
instructions, other terminators, a proper IR representation for
blocks/instructions, etc are all coming.

Semi-affine maps and address spaces are not yet supported (someone want to take
this on?). We also don't generate IR objects for types yet, which I plan to
tackle next.
