instance/class methods metadata.

Still to do:

- Chris will fix a bug in the rewriting engine for nested stmts. For example, the following:

    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; 

tranlates to:

    NSAutoreleasePool * pool = objc_msgSend(objc_msgSend(objc_getClass("NSAutoreleasePool"), sel_getUid("alloc")), sel_getUid("init"))utoreleasePool"), sel_getUid("alloc")) init];

...which is correct, except there is garbage after sel_getUid("init"). This is because the rewriter isn't updating the extent of the containing message expression. 

- Do the crazy cast thang.

protocol meta-data (unlike what documentation says). 2) Include objc.h so,
we can compile the generated metadata with both gcc and clang.

llvm-svn: 43311

Implemented emission of category metadata,

This will make nested subexprs work.

Incorporate some feedback from Chris...

llvm-svn: 43285

Add some plumbing to rewrite message expressions (still under construction).

llvm-svn: 43274

- Add rewrite rule for @class.
- Add setter/getter to ObjcClassDecl.
- Predefined key runtime functions.

we currently turn:

    c = @encode(char *)[2] + 4;

into:

    c = "foo"[2] + 4;

Right now the foo string is hard coded, but you can imagine a world
where it wouldn't be :)

llvm-svn: 43093

@selector probably gets this wrong also.

llvm-svn: 43048

Rename SourceRange::Begin()/End() to getBegin()/getEnd() for
consistency with other code.
Start building the rewriter towards handling @encode.

#import to #include's as a test.

llvm-svn: 43041

$ clang rewrite.c -rewrite-test
prints:

int foo() {
        b:      foo();
f:      foo();
    foo();
}

for:

int foo() {
	b:	foo();
f:	foo();
    foo();
}

amazing.

some incredibly subtle details that I'm working on getting
right.

with x's for now.  The APIs are all unimplemented, so it doesn't do 
anything yet! :)
