f9da10ce45 Change to assert(0,x) to llvm_unreachable(x)
This avoids fall-through error in opt mode:
error: unannotated fall-through between switch labels
[-Werror,-Wimplicit-fallthrough]

b0dabbd67f Add parsing for attributes and attibutes on operations. Add IR representation
for attributes on operations.  Split Operation out from OperationInst so it
can be shared with OperationStmt one day.

6af866c58d Enhance the type system to support arbitrary precision integers, which are
important for low-bitwidth inference cases and hardware synthesis targets.

Rename 'int' to 'affineint' to avoid confusion between "the integers" and "the int
type".

fdf7bc4e25 [WIP] Sketching IR and parsing support for affine maps, affine expressions
Run test case:

$ mlir-opt test/IR/parser-affine-map.mlir
test/IR/parser-affine-map.mlir:3:30: error: expect '(' at start of map range
#hello_world2 (i, j) [s0] -> i+s0, j)

509da7907e Refactor information about tokens out into a new TokenKinds.def file. Use this
to share code a bit more, and fixes a diagnostic bug Uday pointed out where
parseCommaSeparatedList would print the wrong diagnostic when the end signifier
was not a ).

1734d78f88 Sketch out parser/IR support for OperationInst, and a new Instruction base
class.

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

23b784a1bb Implement parser and lexer support for most of the type grammar.
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.

9b9f7ff5d4 Implement enough of a lexer and parser for MLIR to parse extfunc's without
arguments.
