The dependency scanner works with multiple instances of `Compiler{Instance,Invocation}`. From names of the variables/members, their purpose is not obvious.
This patch gives a distinct name to the `CompilerInstance` that's used to run the implicit build during dependency scan.
Depends on D111724.

The `ModuleDepCollectorPP` class holds a reference to `ModuleDepCollector` as well as `ModuleDepCollector`'s `CompilerInstance`. The fact that these refer to the same object is non-obvious.
This patch removes the `CompilerInvocation` reference from `ModuleDepCollectorPP` and accesses it through `ModuleDepCollector` instead.

One of main goals of the dependency scanner is to be strict about module compatibility. This is achieved through strict context hash. This patch ensures that strict context hash is enabled not only during the scan itself (and its minimized implicit build), but also when actually reporting the dependency.

This patch fixes a problem introduced by clang change
https://reviews.llvm.org/D95617 and described by
https://bugs.llvm.org/show_bug.cgi?id=50076#c6, where inlined functions
omit unused parameters both in the stack trace and in `frame var`
command. With this patch, the parameters are listed correctly in the
stack trace and in `frame var` command.
Specifically, we parse formal parameters from the abstract version of
inlined functions and use those formal parameters if they are missing
from the concrete version.

According to the standard [vector.capacity]/5, std::vector<T>::reserve
shall throw an exception of type std::length_error when the requested
capacity exceeds max_size().
This behavior is not implemented correctly: the function 'reserve'
simply propagates the exception from allocator<T>::allocate. Before
D110846 that exception used to be of type std::length_error (which is
correct for vector<T>::reserve, but incorrect for
allocator<T>::allocate).
This patch fixes the issue and adds regression tests.

Add a new serial:// protocol along with SerialPort that provides a new
API to open serial ports. The URL consists of serial device path
followed by URL-style options, e.g.:
serial:///dev/ttyS0?baud=115200&parity=even
If no options are provided, the serial port is only set to raw mode
and the other attributes remain unchanged. Attributes provided via
options are modified to the specified values. Upon closing the serial
port, its original attributes are restored.

In order to explore different variants of reassociation current implementation uses "swap in a loop" approach. Unfortunately, the implementation is more complicated than it could be. This is an attempt to streamline the code. New approach is to extract core functionality into a helper function and call it explicitly as many times as required.

This patch introduces a new function:
AArch64Subtarget::getVScaleForTuning
that returns a value for vscale that can be used for tuning the cost
model when using scalable vectors. The VScaleForTuning option in
AArch64Subtarget is initialised according to the following rules:
1. If the user has specified the CPU to tune for we use that, else
2. If the target CPU was specified we use that, else
3. The tuning is set to "generic".
For CPUs of type "generic" I have assumed that vscale=2.
New tests added here:

If segments are defined in a linker script, placing an orphan section
before the found closest-rank section can result in adding it in a
previous segment and changing flags of that segment. This happens if
the orphan section has a lower sort rank than the found section. To
avoid that, the patch forces orphan sections to be moved after the
found section if segments are explicitly defined.

decl contexts as it seems to be correct and matching our handling of
decl contexts from different modules. It's not required for the fix in

Renamed some variables to distinguish diagnostic like "declaration of

Add following interceptors on Linux: stat, lstat, fstat, fstatat.
This fixes use-of-uninitialized value on platforms with GLIBC 2.33+.
In particular: Arch Linux, Ubuntu hirsute/impish.
The tests should have also been failing during the release on the mentioned platforms, but I cannot find any related discussion.
Most likely, the regression was introduced by glibc commit [[ 8ed005daf0 | 8ed005daf0ab03e14250032 ]]:
all stat-family functions are now exported as shared functions.
Before, some of them (namely stat, lstat, fstat, fstatat) were provided as a part of libc_noshared.a and called their __xstat dopplegangers. This is still true for Debian Sid and earlier Ubuntu's. stat interceptors may be safely provided for them, no problem with that.
