[NFC][Py Reformat] Reformat python files in mlir subdir
This is an ongoing series of commits that are reformatting our
Python code.

Reformatting is done with `black`.

If you end up having problems merging this commit because you
have made changes to a python file, the best way to handle that
is to run git checkout --ours <yourfile> and then reformat it
with black.

If you run into any problems, post to discourse about it and
we will try to help.

514dddbeba [mlir][python] Allow specifying block arg locations
Currently blocks are always created with UnknownLoc's for their arguments. This
adds an `arg_locs` argument to all block creation APIs, which takes an optional
sequence of locations to use, one per block argument. If no locations are
supplied, the current Location context is used.

fa45b2fb2a [mlir][Python] Add __hash__ implementation for Block.
This allows us to hash Blocks and use them in sets or parts of larger
hashable objects. The implementation is the same as other core IR
constructs: the C API object's pointer is hashed.

8d8738f6fe [MLIR] Add block detach func to CAPI and use it in Python bindings
Adds `mlirBlockDetach` to the CAPI to remove a block from its parent
region. Use it in the Python bindings to implement
`Block.append_to(region)`.

3655069234 [mlir] Move the Builtin FuncOp to the Func dialect
This commit moves FuncOp out of the builtin dialect, and into the Func
dialect. This move has been planned in some capacity from the moment
we made FuncOp an operation (years ago). This commit handles the
functional aspects of the move, but various aspects are left untouched
to ease migration: func::FuncOp is re-exported into mlir to reduce
the actual API churn, the assembly format still accepts the unqualified
`func`. These temporary measures will remain for a little while to
simplify migration before being removed.

23aa5a7446 [mlir] Rename the Standard dialect to the Func dialect
The last remaining operations in the standard dialect all revolve around
FuncOp/function related constructs. This patch simply handles the initial
renaming (which by itself is already huge), but there are a large number
of cleanups unlocked/necessary afterwards:

* Removing a bunch of unnecessary dependencies on Func
* Cleaning up the From/ToStandard conversion passes
* Preparing for the move of FuncOp to the Func dialect

ace01605e0 [mlir] Split out a new ControlFlow dialect from Standard
This dialect is intended to model lower level/branch based control-flow constructs. The initial set
of operations are: AssertOp, BranchOp, CondBranchOp, SwitchOp; all split out from the current
standard dialect.

78f2dae00d [mlir][python] Provide some methods and properties for API completeness
When writing the user-facing documentation, I noticed several inconsistencies
and asymmetries in the Python API we provide. Fix them by adding:

- the `owner` property to regions, similarly to blocks;
- the `isinstance` method to any class derived from `PyConcreteAttr`,
  `PyConcreteValue` and `PyConreteAffineExpr`, similar to `PyConcreteType` to
  enable `isa`-like calls without having to handle exceptions;
- a mechanism to create the first block in the region as we could only create
  blocks relative to other blocks, with is impossible in an empty region.

8e6c55c92c [mlir][python] Extend C/Python API to be usable for CFG construction.
* It is pretty clear that no one has tried this yet since it was both incomplete and broken.
* Fixes a symbol hiding issues keeping even the generic builder from constructing an operation with successors.
* Adds ODS support for successors.
* Adds CAPI `mlirBlockGetParentRegion`, `mlirRegionEqual` + tests (and missing test for `mlirBlockGetParentOperation`).
* Adds Python property: `Block.region`.
* Adds Python methods: `Block.create_before` and `Block.create_after`.
* Adds Python property: `InsertionPoint.block`.
* Adds new blocks.py test to verify a plausible CFG construction case.
