When the static type on the Decl side is a subclass of DeclContext the compiler will use a "inlinable" static_cast, instead of always using an out-of-line function call.

Note, though, that the isa<> check still uses an out-of-line function call.

it is probably the most complex version of 'cat' ever invented.

unterminated.

keep comment mode, instead of returning false.  This matches SkipWhitespace.

even whitespace, as tokens from the file.  This is enabled with
L->SetKeepWhitespaceMode(true) on a raw lexer.  In this mode, you too
can use clang as a really complex version of 'cat' with code like this:

  Lexer RawLex(SourceLocation::getFileLoc(SM.getMainFileID(), 0),
               PP.getLangOptions(), File.first, File.second);
  
  RawLex.SetKeepWhitespaceMode(true);
  
  Token RawTok;
  RawLex.LexFromRawLexer(RawTok);
  while (RawTok.isNot(tok::eof)) {
    std::cout << PP.getSpelling(RawTok);
    RawLex.LexFromRawLexer(RawTok);
  }

This will emit exactly the input file, with no canonicalization or other
translation.  Realistic clients actually do something with the tokens of
course :)

same we we do an unterminated string or character literal.  This makes
it so we can guarantee that the lexer never calls into the 
preprocessor (which would be suicide for a raw lexer).

using LexRawToken, create one and use LexFromRawLexer.  This avoids
twiddling the RawLexer flag around and simplifies some code (even 
speeding raw lexing up a tiny bit).

This change also improves the token paster to use a Lexer on the stack
instead of new/deleting it.
