Added config_path variable within the python script which makes the
required call to the clang-tidy binary with --config-file option.
If the config_path is None then config will be used. No error is raised
if both are given but silently chooses config_path over config

The checker removes `const`s that are superfluos and badly affect
readability. `decltype(auto)`/`decltype(expr)` are often const-qualified, but
have no effect on readability and usually can't stop being const-qualified
without significant code change.

Extension to 4390c721 - similar to the vanilla load/store intrinsics, _mm_lddqu_si128/_mm256_lddqu_si256 should take an unaligned pointer, but were using the aligned m128i/m256i types which can cause alignment warnings.

The existing sse3-builtins.c and avx-builtins.c tests in llvm-project\clang\test\CodeGen\X86 should cover this.

When creating an array temporary in the array copy pass, care must be
taken with allocatable components. The element components needs to be
given a clean unallocated status before being used in the assignments.
This is because assignment of allocatable components makes deep copy,
and may cause deallocation of the previous value if it was allocated.
Hence the previous allocation status cannot be let undefined.

On top of that, when cleaning-up the temp, all allocatable components
that may have been allocated must be deallocated.

This patch implements this by centralizing the code making and cleaning
array temps in ArrayValueCopy.cpp, and by calling Initialize and Destroy
runtime entry points when they are allocatable components.

If we already have a AArch64ISD::ANDS node with identical operands, we
can merge any ISD::AND into it, reducing the instruction count by
calculating the value and the flags in a single operation. This code is
taken from the X86 backend, and could also handle AArch64ISD::ADDS and
AArch64ISD::SUBS, but I couldn't find any test cases where it came up.

Migrate to using ReportError to report a failure to evaluate a
watchpoint condition. I had already done so for the parallel code for
breakpoints.

In the process, I noticed that I accidentally regressed the error
reporting for breakpoint conditions by dropping the call to
GetDescription. This patch rectifies that and adds a test.

Because the call to GetDescription expects a Stream*, I also switches
from using a raw_string_ostream to a StreamString for both breakpoints
and watchpoints.

The current dialect registry allows for attaching delayed interfaces, that are added to attrs/dialects/ops/etc.
when the owning dialect gets loaded. This is clunky for quite a few reasons, e.g. each interface type has a
separate tracking structure, and is also quite limiting. This commit refactors this delayed mutation of
dialect constructs into a more general DialectExtension mechanism. This mechanism is essentially a registration
callback that is invoked when a set of dialects have been loaded. This allows for attaching interfaces directly
on the loaded constructs, and also allows for loading new dependent dialects. The latter of which is
extremely useful as it will now enable dependent dialects to only apply in the contexts in which they
are necessary. For example, a dialect dependency can now be conditional on if a user actually needs the
interface that relies on it.

I split up the test so we could stop redirecting stderr to stdout but I

Avoids matching R"mlir( while already inside a string.

This change replaces the manual selection of buffer_atomic_cmpswap*
instructions in SelectionDAG and GlobalISel with a tblgen based
selection in BUFInstructions.td. This allows us to select the return and
no-return variants in tblgen.
