Introduce an off-by default `-Winvalid-utf8` warning
that detects invalid UTF-8 code units sequences in comments.
Invalid UTF-8 in other places is already diagnosed,
as that cannot appear in identifiers and other grammar constructs.
The warning is off by default as its likely to be somewhat disruptive
otherwise.
This warning allows clang to conform to the yet-to be approved WG21
"P2295R5 Support for UTF-8 as a portable source file encoding"
paper.

Bulk remove many of the more trivial uses of ManagedStatic in the llvm

moving the static variable directly into the only function that uses it.

Prevents deadlock between MiniDumpWriteDump and
CryptAcquireContextW (called via fs::createTemporaryFile) in
WriteWindowsDumpFile.
However, there's no guarantee that deadlock can't still occur between
MiniDumpWriteDump and some other Win32 API call. But that would appear
to be the "accepted" risk of using MiniDumpWriteDump in this manner.

Also revert follow-up "[Clang] Fix invalid utf-8 detection"
This reverts commit bf45e27a676d87944f1f13d5f0d0f39935fc4010.
The second commit broke tests, see comments on
https://reviews.llvm.org/D129223, and it sounds like the first
commit isn't valid without the second one. So reverting both for now.
The length of valid codepoints was incorrectly
calculated which was not caught before because the
absence of tests for the valid codepoints scenario.

Add support for the RDPRU instruction on Zen2 processors.
User-facing features:
- Clang option -m[no-]rdpru to enable/disable the feature
- Support is implicit for znver2/znver3 processors
- Preprocessor symbol __RDPRU__ to indicate support
- Header rdpruintrin.h to define intrinsics
- "rdpru" mnemonic supported for assembler code
Internal features:
- Clang builtin __builtin_ia32_rdpru
- IR intrinsic @llvm.x86.rdpru

Instead of dumping the string literal (which
quotes it and escape every non-ascii symbol),
we can use the content of the string when it is a
8 byte string.
Wide, UTF-8/UTF-16/32 strings are still completely
escaped, until we clarify how these entities should
behave (cf https://wg21.link/p2361).
`FormatDiagnostic` is modified to escape
non printable characters and invalid UTF-8.
This ensures that unicode characters, spaces and new
lines are properly rendered in static messages.
This make clang more consistent with other implementation
and fixes this tweet
https://twitter.com/jfbastien/status/1298307325443231744 :)
Of note, `PaddingChecker` did print out new lines that were
later removed by the diagnostic printing code.
To be consistent with its tests, the new lines are removed
from the diagnostic.
Unicode tables updated to both use the Unicode definitions
and the Unicode 14.0 data.
U+00AD SOFT HYPHEN is still considered a print character
to match existing practices in terminals, in addition of
being considered a formatting character as per Unicode.

Implements [[ https://wg21.link/p2071r1 | P2071 Named Universal Character Escapes ]] - as an extension in all language mode, the patch not warn in c++23 mode will be done later once this paper is plenary approved (in July).
We add
* A code generator that transforms `UnicodeData.txt` and `NameAliases.txt` to a space efficient data structure that can be queried in `O(NameLength)`
* A set of functions in `Unicode.h` to query that data, including
* A function to find an exact match of a given Unicode character name
* A function to perform a loose (ignoring case, space, underscore, medial hyphen) matching
* A function returning the best matching codepoint for a given string per edit distance
* Support of `\N{}` escape sequences in String and character Literals, with loose and typos diagnostics/fixits
* Support of `\N{}` as UCN with loose matching diagnostics/fixits.
Loose matching is considered an error to match closely the semantics of P2071.
The generated data contributes to 280kB of data to the binaries.
`UnicodeData.txt` and `NameAliases.txt` are not committed to the repository in this patch, and regenerating the data is a manual process.

Currently the backtrace emitted on windows when llvm-symbolizer is not
available includes addresses which cannot be easily decoded because
the addresses have the containing module's run-time base address added
into them, but we don't know what those base addresses are. This
change emits a module offset rather than an address.
There are a couple of related changes which were included as a result
of the review discussion for this patch:
- I have also removed the parameter printing as it adds noise to the
dump and doesn't seem useful.
- I have added the exception code to the backtrace.
