6edef13569 [mlir:PassOption] Rework ListOption parsing and add support for std::vector/SmallVector options
ListOption currently uses llvm:🆑:list under the hood, but the usages
of ListOption are generally a tad different from llvm:🆑:list. This
commit codifies this by making ListOption implicitly comma separated,
and removes the explicit flag set for all of the current list options.
The new parsing for comma separation of ListOption also adds in support
for skipping over delimited sub-ranges (i.e. {}, [], (), "", ''). This
more easily supports nested options that use those as part of the
format, and this constraint (balanced delimiters) is already codified
in the syntax of pass pipelines.

See https://discourse.llvm.org/t/list-of-lists-pass-option/5950 for
related discussion

63bdcaf92a [mlir][sparse] Moving delete coo into codegen instead of runtime library
Prior to this change there were a number of places where the allocation and deallocation of SparseTensorCOO objects were not cleanly paired, leading to inconsistencies regarding whether each function released its tensor/coo arguments or not, as well as making it easy to run afoul of memory leaks, use-after-free, or double-free errors.  This change cleans up the codegen vs runtime boundary to resolve those issues.  Now, the only time the runtime library frees an object is either (a) because it's a function explicitly designed to do so, or (b) because the allocated object is entirely local to the function and would be a memory leak if not released.  Thus, now the codegen takes complete responsibility for releasing any objects it caused to be allocated.

65bdeddb1e [mlir] Bubble up tensor.extract_slice above linalg operation
Bubble up extract_slice above Linalg operation.

A sequence of operations

    %0 = linalg.<op> ... arg0, arg1, ...
    %1 = tensor.extract_slice %0 ...

can be replaced with

    %0 = tensor.extract_slice %arg0
    %1 = tensor.extract_slice %arg1
    %2 = linalg.<op> ... %0, %1, ...

This results in the reduce computation of the linalg operation.

The implementation uses the tiling utility functions. One difference
from the tiling process is that we don't need to insert the checking
code for the out-of-bound accesses. The use of the slice itself
represents that the code writer is sure about the boundary condition.
To avoid adding the boundary condtion check code, `omitPartialTileCheck`
is introduced for the tiling utility functions.

b73f1d2c5d [mlir][cf-sink] Accept a callback for sinking operations
(This was a TODO from the initial patch).

The control-flow sink utility accepts a callback that is used to sink an operation into a region.
The `moveIntoRegion` is called on the same operation and region that return true for `shouldMoveIntoRegion`.
The callback must preserve the dominance of the operation within the region. In the default control-flow
sink implementation, this is moving the operation to the start of the entry block.

Pure producer consumer fusion thus shall not fuse the producer of a shape-only tensor. In particular, since the shape-only tensor will have other uses that actually consume the data.

The revision enables fusion for consumers that have two uses of the same tensor. One as input operand and one as shape-only output operand. In these cases, we want to fuse only the input operand and avoid output fusion via iteration argument.
