[mlir][bufferization] Better handling of unranked tensors in resolveTensorOpOperandConflicts

Unranked tensors can currently not be copied. They are forced to always bufferize in-place. There is typically some other OpOperand that can bufferize out-of-place instead if needed.

Note: There is IR that cannot be bufferized with One-Shot Bufferize at the moment (see invalid test case). But it is unclear if we need to support such cases. We do not have a use case at the moment. This restriction could be loosened in the future if needed.

This change improves error handling when bufferizing IR where an unranked tensor would be copied. It also disables an optimization where an OpResult was copied instead of an OpOperand in case the OpResult is an unranked tensor (Github #60187).

17 months ago[UTC] Add --version argument

[UTC] Add --version argument

We have a number of pending changes to update_test_checks.py
(and friends) that are essentially blocked on test churn:
If the output of UTC for an existing flag combination changes,
then the next time a test is regenerated, it will contain many
spurious changes. This makes changes to UTC default
behavior essentially impossible.

Examples of such changes are:

* D133943/D142373 want --function-signature to also check the
  return type/attributes.
* D139006/D140212 want to make --function-signature the default
  behavior.
* D142452 wants to add wildcards for block labels.

This patch tries to resolve this issue by adding a --version
argument, which works as follows:

* When regenerating an old test, the default version is 1.
* When generating a new test, the default version is the newest.
 When an explicit version is specified, that of course wins.

This means that any currently existing tests will keep using
--version 1 format, while any new tests will automatically embed
--version N where N is the latest version, and then keep using
that test format from then on.

This patch only implements the --version flag without bumping
the default version, so it does not have any visible behavior
change by itself.

[clang] Add the check of membership in decltype for the issue #58674

D137531 had once fixed the issue. However, it caused a crash during compiling
llvm/unittests/IR/PatternMatch.cpp in stage-2. The reason is the predicator
isDerivedFrom does not consider independent types if the derived type is
dependent.

This patch improves D137531 by adding an option to make isDerivedFrom consider
independent types.
