[PATCH] Added Lexer::getBufferEnd().

[Alexander Kornienko]

Hi jordan_rose,

There's Lexer::getBufferStart(), and we need getBufferEnd() to access
the whole input buffer in clang::format::reformat. We don't want to
rely on the fact that the Lexer::BufferEnd always points to '\0', as there can
be embedded '\0's as well.
