resolver support.
Still TODO are verifier support (to make sure you don't use an attribute for a
function in another module) and the TODO in ModuleParser::finalizeModule that I
will handle in the next patch.

Prior to this CL, return statement had no explicit representation in MLIR. Now, it is represented as ReturnOp standard operation and is pretty printed according to the return statement syntax. This way statement walkers can process ML function return operands without making special case for them.

encapsulates an operation that is yet to be created. This is a patch towards
custom ops providing create methods that don't need to be templated, allowing
them to move out of line in the future.

generalize the asmprinters handling of pretty names to allow arbitrary sugar to
be dumped on various constructs. Give CFG function arguments nice "arg0" names
like MLFunctions get, and give constant integers pretty names like %c37 for a
constant 377

This is still (intentionally) generating redundant parens for nested tightly
binding expressions, but I think that is reasonable for readability sake.
This also print x-y instead of x-(y*1)

This regresses parser error recovery in some cases (in invalid.mlir) which I'll
consider in a follow-up patch. The important thing in this patch is that the
parse methods in StandardOps.cpp are nice and simple.

- Op classes can now provide customized matchers, allowing specializations
beyond just a name match.
- We now provide default implementations of verify/print hooks, so Op classes
only need to implement them if they're doing custom stuff, and only have to
implement the ones they're interested in.
- "Base" now takes a variadic list of template template arguments, allowing
concrete Op types to avoid passing the Concrete type multiple times.
- Add new ZeroOperands trait.
- Add verification hooks to Zero/One/Two operands and OneResult to check that
ops using them are correctly formed.
- Implement getOperand hooks to zero/one/two operand traits, and
getResult/getType hook to OneResult trait.
- Add a new "constant" op to show some of this off, with a specialization for
the constant case.
This patch also splits op validity checks out to a new test/IR/invalid-ops.mlir
file.
This stubs out support for default asmprinter support. My next planned patch
building on top of this will make asmprinter hooks real and will revise this.

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.

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.
