From C++11, a conforming `size()` method is guaranteed to be a
constant-time function. `empty()` is not _generally_ more efficient than
`size()`. It might even be implemented in terms of `size()`.
----
Notes:
- Microsoft's STL had implemented `empty()` as `return size() == 0`,
until May 2021: https://github.com/microsoft/STL/pull/1836/files
- The time complexity of `size()` (specifically for `std::set`) was
discussed by the library working group in 2007-2009:

We forgot to apply the change to headers in the previous patch,
due to missing "-header-filter" in the run-clang-tidy invocation.

Use IgnoreUnlessSpelledInSource to make the matcher code smaller and
more visibly-related to the code.

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.

Changes mostly address formatting and unification of the style. Use
MarkDown style for inline code snippets and lists. Added some text
for a few checks.
The idea is to move most of the documentation out to separate rST files and have
implementation files refer to the corresponding documentation files.
