[MLIR][BufferResultsToOutParamsPass] Add Option to Modify Public Function's Signature (#167248)

Since https://github.com/llvm/llvm-project/pull/162441,
`buffer-results-to-out-params` transforms `private` functions only.

But, as mentioned in
https://github.com/llvm/llvm-project/pull/162441#issuecomment-3404195242,
this is a breaking change for pipelines handling C code. Our pipeline
@EfficientComputer is also affected by this breaking change.

Therefore, this PR adds an opt-in flag to allow `public` functions to be
transformed by `BufferResultsToOutParamsPass`.

[Flang] Add parser support for prefetch directive (#139702)

Implementation details:
* Recognize prefetch directive in the parser as `!dir$ prefetch ...`
* Unparse the prefetch directive
* Add required tests

Details on the prefetch directive:
`!dir$ prefetch designator[, designator]...`, where the designator list
can be a variable or an array reference. This directive is used to
insert a hint to the code generator to prefetch instructions for
memory references.

[InstCombine] Don't sink if it would require dropping deref assumptions. (#166945)

Currently sinking assumes in instcombine drops assumes if they would
prevent sinking. Removing dereferenceable assumptions earlier on can
inhibit vectorization of early-exit loops in practice.

Special-case deferenceable assumptions so that they block sinking. This
can be combined with a separate change to drop dereferencebale
assumptions after vectorization: https://clang.godbolt.org/z/jGqcx3sbs

Add `RSeqRewriter` to detect code references from `__rseq_cs` section
and ignore function referenced from that section. Code references are
detected via relocations (static or dynamic).

Note that the abort handler is preceded by a 4-byte signature byte
sequence and we cannot relocate the handler without that the signature,
otherwise the application may crash. Thus we are ignoring the function,
i.e. making sure it's not separated from its signature.
