Prior to this patch, using an operation without any results as the location would result in the generation of invalid C++ code. It'd try to format using the result values, which would would end up being an empty string for an operation without any.
This patch fixes that issue by instead using getValueAndRangeUse which handles both ranges as well as the case for an op without any results.

The code assumes that a TypeConstraint in the additional constraints list specifies precisely one argument.
If the user were to not specify any, it'd result in a crash. If given more than one, the additional ones were ignored.
This patch fixes the crash and disallows user errors by adding a check that a single argument is supplied to the TypeConstraint

This is completely unused upstream, and does not really have well defined semantics
on what this is supposed to do/how this fits into the ecosystem. Given that, as part of
splitting up the standard dialect it's best to just remove this behavior, instead of try
to awkwardly fit it somewhere upstream. Downstream users are encouraged to
define their own operations that clearly can define the semantics of this.
This also uncovered several lingering uses of ConstantOp that weren't
updated to use arith::ConstantOp, and worked during conversions because
the constant was removed/converted into something else before
verification.
See https://llvm.discourse.group/t/standard-dialect-the-final-chapter/ for more discussion.

The Utils.cpp file in StandardOps essentially just contains utilities for interacting with arithmetic
operations, and at this point makes more sense as a utility file for the arithemtic dialect.

This is part of the larger effort to split the standard dialect. This will also allow for pruning some
additional dependencies on Standard (done in a followup).

Currently if an operation requires additional verification, it specifies an inline
code block (`let verifier = "blah"`). This is quite problematic for various reasons, e.g.
it requires defining C++ inside of Tablegen which is discouraged when possible, but mainly because
nearly all usages simply forward to a static function `static LogicalResult verify(SomeOp op)`.
This commit adds support for a `hasVerifier` bit field that specifies if an additional verifier
is needed, and when set to `1` declares a `LogicalResult verify()` method for operations to
override. For migration purposes, the existing behavior is untouched. Upstream usages will
be replaced in a followup to keep this patch focused on the hasVerifier implementation.
One main user facing change is that what was one `MyOp::verify` is now `MyOp::verifyInvariants`.
This better matches the name this method is called everywhere else, and also frees up `verify` for
the user defined additional verification. The `verify` function when generated now (for additional
verification) is private to the operation class, which should also help avoid accidental usages after
this switch.

Some FormatElement subclasses contain `std::vector`. Since these use
BumpPtrAllocator, they need to be converted to trailing objects.
However, this is not a trivial fix so I will leave it as a FIXME and use
a workaround.
Move the functions that retrieve the supporting C library, compile an MLIR
module and build a JIT execution engine to mlir_pytaco_utils.
Add a function to create an MLIR sparse tensor from a file and return a pointer

When attempting to cast a pybind11 handle to an MLIR C API object through
capsules, the binding code would attempt to directly access the "_CAPIPtr"
attribute on the object, leading to a rather obscure AttributeError when the
attribute was missing, e.g., on non-MLIR types. Check for its presence and
throw a TypeError instead.

Somehow the test introduced in https://reviews.llvm.org/D118006 produces the expected result but running
through lli with Intel SDE activated sneaks in an error code 2 (before this commit) or an error code 10
(after this commit).
The test as is is still meaningful in that the LLVMIR generation would crash if the `elementtype` is set
improperly.
Still, this should run with lli turned on.
This revision adds enough support to allow InlineAsmOp to work properly with indirect memory constraints "*m".
These require an explicit "elementtype" TypeAttr on the operands to pass LLVM verification and need to be provided.

Part 2 of 3 of unifying the assembly formats of attributes/types and operations.The last patch that introduced attribute/type formats (D111594) factored out the format lexer entirely. This patch factors out most of the format parsers such that the attribute/type and op parsers only need to implement handling for specific elements.
Certain things could be factored better (element verification, 'seen' variables) but the primary goal of factoring is so that features can be used across both assembly formats.
