This patch changes the return type of `PreprocessorLexer::getFileEntry()` so that its clients may stop using the deprecated APIs of `FileEntry`.

tokens.
We now actually form an angled_string_literal token for a header name by
concatenation rather than just working out what its contents would be.
This substantially simplifies downstream processing and is necessary for
C++20 header unit imports.

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.

This is similar to the LLVM change https://reviews.llvm.org/D46290.
We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

Before this patch, Lex() would recurse whenever the current lexer changed (e.g.
upon entry into a macro). This patch turns the recursion into a loop: the
various lex routines now don't return a token when the current lexer changes,
and at the top level Preprocessor::Lex() now loops until it finds a token.
Normally, the recursion wouldn't end up being very deep, but the recursion depth
can explode in edge cases like a bunch of consecutive macros which expand to
nothing (like in the testcase test/Preprocessor/macro_expand_empty.c in this
patch).

uncovered.
This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.
I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

This avoids a stack overflow with a sequence of many empty #includes.

Currently getMacroArgExpandedLocation is very inefficient and for the case
of a location pointing at the main file it will end up checking almost all of
the SLocEntries. Make it faster:
-Use a map of macro argument chunks to their expanded source location. The map
is for a single source file, it's stored in the file's ContentCache and lazily
computed, like the source lines cache.
-In SLocEntry's FileInfo add an 'unsigned NumCreatedFIDs' field that keeps track
of the number of FileIDs (files and macros) that were created during preprocessing
of that particular file SLocEntry. This is useful when computing the macro argument
map in skipping included files while scanning for macro arg FileIDs that lexed from
a specific source file. Due to padding, the new field does not increase the size
of SLocEntry.

The previous name was inaccurate as this token in fact appears at
the end of every preprocessing directive, not just macro definitions.
No functionality change, except for a diagnostic tweak.

"FileID" a concept that is now enforced by the compiler's type checker
instead of yet-another-random-unsigned floating around.
This is an important distinction from the "FileID" currently tracked by
SourceLocation. *That* FileID may refer to the start of a file or to a
chunk within it. The new FileID *only* refers to the file (and its
#include stack and eventually #line data), it cannot refer to a chunk.
FileID is a completely opaque datatype to all clients, only SourceManager
is allowed to poke and prod it.

Performance testing of -Eonly on Cocoa.h shows no performance regression because

PreprocessorLexer now has a virtual method "IndirectLex" which allows it to call the lex method of its subclasses. This is not for performance intensive operations.
