The goal of this commit is to fix clang-format so it does not merge tokens when
using the alternative spelling keywords. (eg: "not foo" should not become "notfoo")

The problem is that Preprocessor::HandleIdentifier used to drop the identifier info
from the token for these keyword. This means the first condition of
TokenAnnotator::spaceRequiredBefore is not met. We could add explicit check for
the spelling in that condition, but I think it is better to keep the IdentifierInfo
and handle the operator keyword explicitly when needed. That actually leads to simpler
code, and probably slightly more efficient as well.

Another side effect of this change is that __identifier(and) will now work as
one would expect, removing a FIXME from the MicrosoftExtensions.cpp test

Welcome to Clang.  This is a compiler front-end for the C family of languages
(C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM
compiler infrastructure project.

Unlike many other compiler frontends, Clang is useful for a number of things
beyond just compiling code: we intend for Clang to be host to a number of
different source-level tools.  One example of this is the Clang Static Analyzer.

If you're interested in more (including how to build Clang) it is best to read
the relevant web sites.  Here are some pointers:
