Implement more efficient Decl <-> DeclContext conversions.
...
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.

Add a new mode to the lexer which enables it to return all characters,
...
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 :)

Simplify raw mode lexing by treating an unterminate /**/ comment the

same we we do an unterminated string or character literal. This makes
it so we can guarantee that the lexer never calls into the

Change how raw lexers are handled: instead of creating them and then
...
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.
