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.

Extend set of return registers on sparc until someone will implement MRV support there. At least, this will allow libgcc compile, however we are not ABI-compatible with stuff compiled with native gcc.
