8b5a3e4632 [MLIR] Change FuncOp assembly syntax to print visibility inline instead of in attrib dict.
- Change syntax for FuncOp to be `func <visibility>? @name` instead of printing the
  visibility in the attribute dictionary.
- Since printFunctionLikeOp() and parseFunctionLikeOp() are also used by other
  operations, make the "inline visibility" an opt-in feature.
- Updated unit test to use and check the new syntax.

a0d5e54966 [MLIR] Update tutorial to add missing tests and bring directory paths and code snippets up to date.
Summary:
The tests referred to in Chapter 3 of the tutorial were missing from the tutorial test
directory; this adds those missing tests. This also cleans up some stale directory paths and code
snippets used throughout the tutorial.

cb530ec8b8 [mlir][Tutorial] Make parsing an empty file print a better error.
Summary:
Previously, we would, for an empty file, print the somewhat confusing
  Assertion `tok == curTok [...]' failed.
With this change, we now print
  Parse error [...]: expected 'def' [...]

This only affects the parser from chapters 1-6, since the more advanced
chapter 7 parser is actually able to generate an empty module from an
empty file.  Nonetheless, this commit also adds the additional check to
the chapter 7 parser, for consistency.

0050e8f0cf [mlir][Tutorial] Add a section to Toy Ch.2 detailing the custom assembly format.
Summary:
This details the C++ format as well as the new declarative format. This has been one of the major missing pieces from the toy tutorial.

57540c96be [mlir] Replace toy::DeadFunctionEliminationPass with symbolDCEPass.
Summary:
The dead function elimination pass in toy was a temporary stopgap until we had proper dead function elimination support in MLIR. Now that this functionality is available, this pass is no longer necessary.

The transpose in the example had the same result type as its input, which is incorrect.

1ba9bb0507 Add Ch.5 of the toy tutorial.
This chapter adds a partial lowering of toy operations, all but PrintOp, to a combination of the Affine and Std dialects. This chapter focuses on introducing the conversion framework, the benefits of partial lowering, and how easily dialects may co-exist in the IR.

8c2ea32072 Emit LLVM IR equivalent of sizeof when lowering alloc operations
Originally, the lowering of `alloc` operations has been computing the number of
bytes to allocate when lowering based on the properties of MLIR type. This does
not take into account type legalization that happens when compiling LLVM IR
down to target assembly. This legalization can widen the type, potentially
leading to out-of-bounds accesses to `alloc`ed data due to mismatches between
address computation that takes the widening into account and allocation that
does not. Use the LLVM IR's equivalent of `sizeof` to compute the number of
bytes to be allocated:
  %0 = getelementptr %type* null, %indexType 0
  %1 = ptrtoint %type* %0 to %indexType

679a3b4191 Change the attribute dictionary syntax to separate name and value with '='.
The current syntax separates the name and value with ':', but ':' is already overloaded by several other things(e.g. trailing types). This makes the syntax difficult to parse in some situtations:

Old:
  "foo: 10 : i32"

New:
  "foo = 10 : i32"

4842b2d42e Modify the syntax of the the ElementsAttrs to print the type as a colon type.
This is the standard syntax for types on operations, and is also already used by IntegerAttr and FloatAttr.

Example:
  dense<5> : tensor<i32>
  dense<[3]> : tensor<1xi32>

b5a34406a8 Update the Parser to support parsing/printing DenseElementAttrs with a splat value. The syntax for this is the same as 0-D tensors:

  dense<tensor<1x1x1xi64>, -5>
