The code in ObjectFileMachO didn't disambiguate between ios and
ios-simulator object files for Mach-O objects using the legacy
ambiguous LC_VERSION_MIN load commands. This used to not matter before
taught ArchSpec that ios and ios-simulator are no longer compatible.

Summary:
Initially, Apple simulator binarie triples didn't use a `-simulator`
environment and were just differentiated based on the architecture.
For example, `x86_64-apple-ios` would obviously be a simualtor as iOS
doesn't run on x86_64. With Catalyst, we made the disctinction
explicit and today, all simulator triples (even the legacy ones) are
constructed with an environment. This is especially important on Apple
Silicon were the architecture is not different from the one of the
simulated device.
This change makes the simulator part of the environment always part of
the criteria to detect whether 2 `ArchSpec`s are equal or compatible.

Add YAML traits for ArchSpec and ProcessInstanceInfo so they can be
serialized for the reproducers.

Summary:
A *.cpp file header in LLDB (and in LLDB) should like this:
```
//===-- TestUtilities.cpp -------------------------------------------------===//
```
However in LLDB most of our source files have arbitrary changes to this format and
these changes are spreading through LLDB as folks usually just use the existing
source files as templates for their new files (most notably the unnecessary
editor language indicator `-*- C++ -*-` is spreading and in every review
someone is pointing out that this is wrong, resulting in people pointing out that this
is done in the same way in other files).
This patch removes most of these inconsistencies including the editor language indicators,
all the different missing/additional '-' characters, files that center the file name, missing
trailing `===//` (mostly caused by clang-format breaking the line).

Summary:
This patch fixes a bug where when target triple created from elf information
is arm-*-linux-eabihf and platform triple is armv8l-*-linux-gnueabihf. Merging
both triple results in armv8l--unknown-unknown.
This happens because we order a triple update while calling CoreUpdated and
CoreUpdated creates a new triple with no vendor or environment information.
Making sure we do not update triple and just update to more specific core
fixes the issue.

Previous ArchSpec tests didn't catch this bug since we never tested just the OS being out of date. Fixed the bug and covered this with a test that would catch this.
This was found when trying to load a core file where the core file was an ELF file with just the e_machine for architeture and where the ELF header had no OS set in the OSABI field of the e_ident. It wasn't merging the architecture with the target architecture correctly.

Summary:
This behavior was originally added in rL252264 (git commit 76a7f365da)
in order to be extra careful with handling platforms like watchos and tvos.
However, as far as triples go, those two (and others) are treated as OSes and
not environments, so that should not really apply here.
Additionally, this behavior is incorrect and can lead to incorrect ArchSpecs.
Because android is specified as an environment and not an OS, not propogating
the environment can lead to modules and targets being misidentified.

Summary:
These functions should always return the opposite of the
`Triple{Environment,OS,Vendor}WasSpecified` functions. Unspecified unknown is
the same as unspecified, which is why one set of functions should give us what
we want. It's possible to have specified unknown, which is why we can't just
rely on checking the enum values of vendor/os/environment. We must also ensure
that the names of these are empty and not "unknown".

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
instead of returning the architecture through by-ref argument and a
boolean value indicating success, we can just return the ArchSpec
directly. Since the ArchSpec already has an invalid state, it can be
used to denote the failure without the additional bool.

The rationale here is that ArchSpec is used throughout the codebase,
including in places which should not depend on the rest of the code in
the Core module.
This commit touches many files, but most of it is just renaming of
#include lines. In a couple of cases, I removed the #include ArchSpec
line altogether, as the file was not using it. In one or two places,
this necessitated adding other #includes like lldb-private-defines.h.
