Refactors operation parsing to share functionality between CFG and ML functions. ML function construction now goes through a builder, similar to the way it is done for
CFG functions.

Allows printing the instruction to string without trailing newline. Making it easier to reuse print to annotate instructions during lowering. And removes need for newline in the print functions of ops.

use it.
This also removes "operand" from the affine expr classes: it is unnecessary
verbosity and "operand" will mean something very specific for SSA stuff (we
will have an Operand type).

- check for non-affine expressions
- handle negative numbers and negation of id's, expressions
- functions to check if a map is pure affine or semi-affine
- simplify/clean up affine map parsing code
- report more errors messages, more accurate error messages

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).)

in a container automatically maintain their parent pointers, and change storage
from std::vector to the proper llvm::iplist type.

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

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.
