The implementation of the template instantiation of requires expressions
was incorrectly trying to get the expression from an 'ExprRequirement'
before checking if it was an error state.

See PR47174.
When canonicalizing nested name specifiers of the type kind,
the prefix for 'DependentTemplateSpecialization' types was being
dropped, leading to malformed types which would cause failures
when rebuilding template names.

If the vectorized insertelements instructions form indentity subvector
(the subvector at the beginning of the long vector), it is just enough
to extend the vector itself, no need to generate inserting subvector

This patch tries to fix command line too long problem on Windows for

The command line is too long with check_clang_tidy.py program on Windows,
because the configuration is long for regression test. Fix this issue by
passing the settings in file instead.

where should not.
Currently we are using QTy->isIncompleteType(&ND) to check incomplete
type. But before doing that, need to instantiate for a class template
specialization or a class member of a class template specialization,
or an array with known size of such..., so that we know it is really
incomplete type.
To fix this using RequireCompleteType instead.
The new test is added into "test/OpenMP/target_update_messages.cpp"
The different of using RequireCompleteType is when emit incomplete type,
an additional note is also emitted to point to where incomplete type
is declared. Because this change, many tests are needed to be fixed
by adding additional note.

This change supports to run without parsing MMap binary loading events instead it always assumes binary is loaded at the preferred address. This is used when we have assured no binary load address changes or we have pre-processed the addresses resolution. Warn if there's interior mmap event but without leading mmap events.

This changes the lowering of f32 and f64 COPY from a 128bit vector ORR to
a fmov of the appropriate type. At least on some CPU's with 64bit NEON
data paths this is expected to be faster, and shouldn't be slower on any
CPU that treats fmov as a register rename.

This is available in GNU ld 2.35 and can be seen as a shortcut for multiple

In the long term, this option probably should be preferred over --dynamic-list.

A `Vector` that doesn't require an initial `reserve()` (eg: with a
default, or small enough capacity) can have a constant initializer.
This changes the code in a few places to make that possible:
- mark a few other functions as `constexpr`
- do without any `reinterpret_cast`
- allow to skip `reserve` from `init`

Eliminated references from task dependency hash to node allocated on stack,
thus eliminated accesses to stale memory. So the node now never freed.

The inttoptr/ptrtoint roundtrip optimization is not always correct.
We are working towards removing this optimization and adding support to specific cases where this optimization works.
In this patch, we focus on phi-node operands with inttoptr casts.
We know that ptrtoint( inttoptr( ptrtoint x) ) is same as ptrtoint (x).
So, we want to remove this roundtrip cast which goes through phi-node.
