[lldb] Fix Error/assert.test regression with symbols

LLDB on Linux built with symbols is showing this error.
Without symbols it still PASSes:
  lldb-test: .../lldb/source/Utility/LLDBAssert.cpp:29: void lldb_private::lldb_assert(bool, const char *, const char *, const char *, unsigned int): Assertion `false && "lldb_assert failed"' failed.

With symbols it FAILs:
  lldb-test: .../lldb/tools/lldb-test/lldb-test.cpp:1086: int opts::assert::lldb_assert(lldb_private::Debugger &): Assertion `false && "lldb-test assert"' failed.

MLIR][STD] Fold trunci (sexti).

This patch folds the following pattern:

```
%arg0 = ...
%0 = sexti %arg0 : i1 to i8
%1 = trunci %0 : i8 to i1
```

into just `%arg0`.

[ARM] Extend MVE lane interleaving to handle other non-instruction leaves

This extends the recent MVE lane interleaving passto handle other
non-instruction leaves, for which a new shuffle is added. This helps
especially for constants and potentially for arguments.

[mlir] Introduce CloneOp and adapt test cases in BufferDeallocation.

Add a new clone operation to the memref dialect. This operation implicitly
copies data from a source buffer to a new buffer. In contrast to the linalg.copy
operation, this operation does not accept a target buffer as an argument.
Instead, this operation performs a conceptual allocation which does not need to
be performed manually.

Furthermore, this operation resolves the dependency from the linalg-dialect
in the BufferDeallocation pass. In addition, we also extended the canonicalization
patterns to fold clone operations. The copy removal pass has been removed.

[lldb] Don't search for system specific strings in assert.test

Commit 6bc1e69de270db8d7191200f54158e4192f997ba changed the search string
to also check for the generated strings that surround the plain assert:

    Assertion `false && "lldb-test assert"' failed
                                         ^^^^^^^^^

This causes the test to fail on setups where the generated assert message
looks different. E.g., on macOS the generated message looks like this:

    Assertion failed: (false && "lldb_assert failed"), function lldb_assert

This reverts the old behaviour of just checking for the actual string we
have inside LLDB.

[Orc][tests] Moving one MCJIT test over to Orc to make sure the PowerPC fix worked

The PowerPC fix landed in d9069dd9b576. This is in preparation for D98931.

[SVE][Analysis]Instruction costs for ops on scalable-vec

The following operations have no associated cost for them
when applied to scalable vectors, and as a consequence
can trigger a crash when a call is made to
AArch64TTIImpl::getCastInstrCost():
- fptrunc
- trunc
- fpext
- fpto(u,s)i

This patch adds costs for these operations and
relevant regression tests.

[X86][SSE] combineHorizOpWithShuffle - consistently use getTargetShuffleInputs to decode shuffles

Minor cleanup before I start trying to merge the unary/binary shuffle combining paths.

[X86] Regenerate tests to add missing @PLT

[X86][F16C] Add F16C -O0 test coverage

Ensure the duplicate conversions noticed in D48614 have gone

Revert "Reapply "OpaquePtr: Turn inalloca into a type attribute""

Reverting because test 'Bindings/Go/go.test' is failing on most
buildbots.

This reverts commit fc9df309917e57de704f3ce4372138a8d4a23d7a.

[lldb][NFC] Add a test case for Objective-C properties with conflicting names

This is an LLDB test for the ASTImporter crash that got fixed in D99077.
The test is using Clang modules for the properties as it seems the conflicting
names are not actually correctly handled when generating debug information
(only the first property is emitted and the second one is ignored in the current
clang ToT).

Revert "[mlir] Introduce CloneOp and adapt test cases in BufferDeallocation."

This reverts commit 06b03800f3fcbf49f5ddd4145b40f04e4ba4eb42.
Until some kind of support for region args is added.

Don't use $ as suffix for symbol names in ThinLTOBitcodeWriter and other places

Using $ breaks demangling of the symbols. For example,

$ c++filt _Z3foov\$123
_Z3foov$123

This causes problems for developers who would like to see nice stack traces
etc., but also for automatic crash tracking systems which try to organize
crashes based on the stack traces.

Instead, use the period as suffix separator, since Itanium demanglers normally
ignore such suffixes:

$ c++filt _Z3foov.123
foo() [clone .123]

This is already done in some places; try to do it everywhere.
