Don't call raw_string_ostream::flush(), which is essentially a no-op.
As specified in the docs, raw_string_ostream is always unbuffered

SourceManager.h includes FileManager.h, which is expensive due to
dependencies on LLVM FS headers.
Remove dead BeforeThanCompare specialization.
Sink ASTContext::addComment to cpp file.
This reduces the time to compile a file that does nothing but include
ASTContext.h from ~3.4s to ~2.8s for me.
Saves these includes:

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.

Summary:
This moves the data collection macro calls for Stmt nodes
to lib/AST/StmtDataCollectors.inc
Users can subclass ConstStmtVisitor and include StmtDataCollectors.inc
to define visitor methods for each Stmt subclass. This makes it also
possible to customize the visit methods as exemplified in
lib/Analysis/CloneDetection.cpp.
Move helper methods for data collection to a new module,
AST/DataCollection.
Add data collection for DeclRefExpr, MemberExpr and some literals.
