f6a3bda65e make the -rewrite-test a bit more interesting: it now 
wraps comments in <i> tags.  Extend rewrite tokens to support
this minimal functionality.

b6aa53b7de start implementing a token rewriter. At this point, it just reads in a file 
and lets a client iterate over it.

1782da2f84 Add a new -rewrite-test option, which is basically a 
playground to experiment with some new rewriter approaches. For now
it is probably the most complex version of 'cat' ever invented.

fc7d4a3bd2 Add a new -dump-raw-tokens option, which allows us to see raw tokens. 
Rename -dumptokens to -dump-tokens.

50c9050037 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.

415d3d570a - Add BlockDecl AST node. 
- Modify BlockExpr to reference the BlockDecl.

This is "cleanup" necessary to improve our lookup semantics for blocks (to fix <rdar://problem/6272905> clang block rewriter: parameter to function not imported into block?).

Still some follow-up work to finish this (forthcoming).

db7f2a74db Explicitly access the first Decl* referenced by a DeclStmt instead of using "getDecl()." Added a FIXME indicating that the call to RewriteObjCQualifiedInterfaceTypes() is meant to modifying the type-specifier; hopefully this will be a little more clean once DeclGroups contain type specifiers.

53532c1fda In RewriteFunctionBody, using DeclStmt::decl_iterator to rewrite the Decls in a DeclStmt instead of using getDecl() to fetch the first Decl. 
Steve: Please review this patch.  'make test' passes, and my cursory scan of the rewriter leads me to believe this doesn't break anything, but I'm not sure.

5f96e4dffc Moved main control flow functions to bottom of file. 
Reworked control flow to:
- rewrite the block expr body "in place".
- used Chris's new rewriter hook "getRewritenText" to "lift" the text for later use.
- finally, we do the block expr text replacement.

87930ca38f Teach block rewriter to replace '^' with '*' in VarDecls. 
Since we don't have DeclGroup's and location information for types, there is some fancy footwork to do this fairly reliably.

O.K...it's a kludge. One day, we can use this as motivation to do this more gracefully:-)
