The ZeroWidth paramter is unused in every call site of VerifyBitField.

Previously, we were treating a move in the lambda capture as if it happened
within the body of the lambda, not within the function that defines the lambda.

This fixes the same bug as https://reviews.llvm.org/D119165 (which it appears
may have been abandoned by the author?) but does so more simply.

and they bufferize to equivalent buffers in the absence of other conflicts.
`scf.foreach_thread.parallel_insert_slice` conflict detection is similar to `tensor.insert_slice` conflict detection.

This patch is trying to fix issue 48588(https://github.com/llvm/llvm-project/issues/48588)

I found the results of Instruction Selection between SelectionDAG and FastISEL for the `%mul = mul i32 %A, 4294967295`:
(seldag-isel) mul --> sub --> SUB32dp

My patch to fix this issue is by overriding a virtual function M68kDAGToDAGISel::IsProfitableToFold(). Return `false` when it was trying to match with SUB, then it will match with NEG.

The immediate range check for CSImm12MulBy8 included some values
covered by CSImm12MulBy4. I assume CSImm12MulBy4 had priority due
to pattern order in the td file, but this makes the priority
explicit in the predicate.

echo.ll is unchanged to test typed pointers.

These effectively all share the same implementation, i.e. forward
to the non-templated overload and then construct the container op.

Since version 0.7 we've added:

* Initial language support for TableGen
* Tweaked syntax highlighting for PDLL
* Added a new command to view intermediate PDLL output

This commit enables providing long-form documentation more seamlessly to the LSP
by revamping decl documentation. For ODS imported constructs, we now also import
descriptions and attach them to decls when possible. For PDLL constructs, the LSP will
now try to provide documentation by parsing the comments directly above the decls
location within the source file. This commit also adds a new parser flag
`enableDocumentation` that gates the import and attachment of ODS documentation,
which is unnecessary in the normal build process (i.e. it should only be used/consumed
by tools).

This patch proposed to use a new cost model for loop interchange, which
is obtained from loop cache analysis.

Given a loopnest, what loop cache analysis returns is a vector of loops
[loop0, loop1, loop2, ...] where loop0 should be replaced as the outermost
loop, loop1 should be placed one more level inside, and loop2 one more level
inside, etc. What loop cache analysis does is not only more comprehensive than
the current cost model, it is also a "one-shot" query which means that we only
need to query it once during the entire loop interchange pass, which is better
than the current cost model where we query it every time we check whether it is
profitable to interchange two loops. Thus complexity is reduced, especially after
D120386 where we do more interchanges to get the globally optimal loop access pattern.

Updates made to test cases are mostly minor changes and some corrections.
Test coverage for loop interchange is not reduced.

Currently we did not completely remove the legacy cost model, but keep it as
fall-back in case the new cost model did not run successfully. This is because
currently we have some limitations in delinearization, which sometimes makes
loop cache analysis bail out. The longer term goal is to enhance delinearization
and eventually remove the legacy cost model compeletely.
