clang-format: [JS] fix uninitialized memory.

SortJavaScriptImports attempts to set its currently parsed token to an
invalid token when it reaches the end of the line. However in doing so,
it used a `FormatToken`, which contains a `Token Tok`. `Token` does not
have a constructor, so its fields start out as uninitialized memory.

`Token::startToken()` initializes all fields. Calling it in
`JavaScriptImportSorter`'s constructor thus fixes the problem.

With this change, aliases sort as their own group, coming last after all
other imports.

Aliases are not sorted within their group, as they may reference each
other, so order is significant.

Make clang-format fuzz through Lexing with asserts enabled.

Makes clang-format bail out if an in-memory source file with an
unsupported BOM is handed in instead of creating source locations that
are violating clang's assumptions.

In the future, we should add support to better transport error messages
like this through clang-format instead of printing to stderr and not
creating any changes.

clang-format: [JS] handle "off" in imports

Previously, the JavaScript import sorter would ignore `// clang-format
off` and `on` comments. This change fixes that. It tracks whether
formatting is enabled for a stretch of imports, and then only sorts and
merges the imports where formatting is enabled, in individual chunks.

This means that there's no meaningful total order when module references are mixed
with blocks that have formatting disabled. The alternative approach
would have been to sort all imports that have formatting enabled in one
group. However that raises the question where to insert the
formatting-off block, which can also impact symbol visibility (in
particular for exports). In practice, sorting in chunks probably isn't a
big problem.

This change also simplifies the general algorithm: instead of tracking
indices separately and sorting them, it just sorts the vector of module
references. And instead of attempting to do fine grained tracking of
whether the code changed order, it just prints out the module references
text, and compares that to the previous text. Given that source files
typically have dozens, but not even hundreds of imports, the performance
impact seems negligible.

Update the file headers across all of the LLVM projects in the monorepo
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.

We've been running doxygen with the autobrief option for a couple of

redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
