Initial version of formatting library.

This formatting library will be used by a stand-alone clang-format tool
and can also be used when writing other refactorings.

Manuel's original design document:
https://docs.google.com/a/google.com/document/d/1gpckL2U_6QuU9YW2L1ABsc4Fcogn5UngKk7fE5dDOoA/edit

The library can already successfully format itself.

libclangFormat is not libclangTooling, but it depends on it.

Add Clang flags -fsanitize-blacklist and -fno-sanitize-blacklist. Make this flag usable for ASan. Blacklisting can be used to disable sanitizer checks for particular file/function/object.

Fixes a compile warning and crash in the tests.

The necessity of this fix points to a problem with the design
of the addToken during the optimiation phase, which we need to address
in a much more principled way.

Add a 'count' field to the DWARF subrange.

The count field is necessary because there isn't a difference between the 'lo'
and 'hi' attributes for a one-element array and a zero-element array. When the
count is '0', we know that this is a zero-element array. When it's >=1, then
it's a normal constant sized array. When it's -1, then the array is unbounded.

Introduce CompilationDatabase::getAllCompileCommands() that returns all
compile commands of the database and expose it via the libclang API.

[libclang] Avoid copying the CompileCommand related strings when wrapping them to a CXString.

In the PreprocessingRecord, to identify the different conditional directive regions
use the SourceLocation at the start of the respective region, instead of a unique integer.

Refactor recording the preprocessor conditional directive regions out of
PreprocessingRecord and into its own class, PPConditionalDirectiveRecord.

Decoupling allows a client to use the functionality of PPConditionalDirectiveRecord
without needing a PreprocessingRecord.
