This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated. The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.
This is part of an effort to migrate from llvm::Optional to
std::optional:
https://discourse.llvm.org/t/deprecating-llvm-optional-x-hasvalue-getvalue-getvalueor/63716
This gives CommandMangler access to other fields of
tooling::CompileCommand as well, e.g. Directory.

A new option -I is added for dxc mode.
It is just alias of existing cc1 -I option.

MSVC was issuing "illegal conversion; more than one user-defined
conversion has been implicitly applied" as a warning on this code.
Explicitly calling .str() causes a StringRef to be materialized so
that a second user-defined conversion is not required.
* Suppress a lot of `-Wtautological-compare` warning
* Speed up file build a little bit

"driver <flags> -- <input>" is a particularly convenient form of the
compile command to manipulate, with fewer special cases to handle.
Guaranteeing that the output command is of that form is cheap and makes
it easier to consume the result in some cases.

It's reasonable to want to use the command from one file to compile another.
In particular, the command from a translation unit to parse a related header:
{"file": "foo.h", "command": "clang foo.cpp"}
This is largely what InterpolatingCompilationDatabase tries to do.
To do this correctly can require nontrivial changes to the argv, because the
file extension affects semantics. e.g. here we must add "-x c++header".
When external tools compile commands for different files, we should apply the
same adjustments. This is better than telling people to "fix their tools":
- simple e.g. python scripts shouldn't have to interpret clang argv
- this is a good way to represent the intent "parse header X in the context of
file Y", which can work even if X is not self-contained. clangd does not
support this today, but some other tools do, and we may one day.

We already strip all the inputs provided without `--`, this patch also
handles the cases with `--`.

This patch strips all the arch options in case of multiple ones. As it
results in multiple compiler jobs, which clangd cannot handle.
It doesn't pick any over the others as it is unclear which one the user wants
and defaulting to host architecture seems less surprising. Users also have the
ability to explicitly specify the architecture they want via clangd config
files.
Fixes https://github.com/clangd/clangd/issues/827.

Pushes input for the compile action to the end while separating with a
`--` before applying other manglings. This ensures edits that effect only the
arguments that come after them works, like changing parse language via -x.

Dummy is a word with inappropriate associations. This patch updates the
references to it in clangd code base with more precise ones.
The only user-visible change is the default variable name used when extracting a
variable. It will be named as `placeholder` from now on.

Summary:
This is designed for tweaking compile commands by specifying flags to add/remove
in a config file. Something like:
CompileFlags: { Remove: -fcolor-diagnostics }
Having users tweak raw argv (e.g. with a regex) is going to end in tears: bugs
around clang-cl, xclang, aliases, joined-vs-separate args etc are inevitable.
This isn't in tooling because of the performance choices: build a big table
up-front to make subsequent actions fast. Maybe it should be though.

Summary:
This introduces the "semantic form" of config exposed to features,
contrasted with the "syntactic form" exposed to users in e9fb1506b8.
The two are not connected, CompiledFragment and Provider will bridge that gap.
Nor is configuration actually set: that needs changes to ClangdServer,
TUScheduler, and BackgroundQueue.

Summary:
This fixes a reported bug: if clang and libc++ are installed under
/usr/lib/llvm-11/... but there'- a symlink /usr/bin/clang++-11, then a
compile_commands.json with "/usr/bin/clang++-11 -stdlib=libc++" would previously
look for libc++ under /usr/include instead of /usr/lib/llvm-11/include.
The PATH change makes this work if the compiler is just "clang++-11" too.
As this is now doing IO potentially on every getCompileCommand(), we cache
the results for each distinct driver.
While here:
- Added a Memoize helper for this as multithreaded caching is a bit noisy.
- Used this helper to simplify QueryDriverDatabase and reduce blocking there.
(This makes use of the fact that llvm::Regex is now threadsafe)

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
Summary:
- Since `--sysroot` is a superset of the `-isysroot` argument, we
shouldn't add the `-isysroot` if we detect a `--sysroot` flag.
