Rewrite protocols.

- Add location info to category/protocol AST's
- Rewrite categories.

Remove a couple FIXME's for rewriting ObjC interfaces (which are now being rewritten properly).

llvm-svn: 43494

More support for rewriting ObjC intefaces. Still some edge cases to handle...

Remove a bunch of TODO's that have been done for quite some time...

llvm-svn: 43476

This commit contains lot's of small tweaks to how we pass around and store SourceLocation's for interfaces/protocols/categories/implementations.

llvm-svn: 43475

of VariableArrayTypes that appear in TypedefDecls.

for example:

  typedef int T[x][x];

the StmtIterator will iterate over "x" and "x" as subexpressions of
the DeclStmt for T.

llvm-svn: 43474

where the decl would always be non-NULL.  Moved the check to after the
block to properly tidy up the iterator's state.

llvm-svn: 43473

llvm-svn: 43472

of VariableTypeArray types that appear in DeclStmts.

Removed operator-- from StmtIterator.  operator-- added undesired
complexity, and we have no consumers of it.

llvm-svn: 43471

iterator of a CompountStmt instead of relying on StmtIterators.

llvm-svn: 43469

slightly more succinct.

Introduced VariableArrayType* within StmtIteratorBase to (soon)
support iteration over the size expressions of variable length arrays.

Moved a dependent predicate in an if statement to be an assertion
within the if statement body.

llvm-svn: 43453

should emit warnings.

llvm-svn: 43451

"x == x" and "x != x".  We emit a warning for these since they always evaluate
to a constant value and often indicate a logical error.

Added test case for this check.

an unimplemented work  and continue.

llvm-svn: 43449

(x) == x  is the treated the same as x == x.

llvm-svn: 43448

errors for cases such as "x == x".

Added test case to test this feature.

a bogus secondary warning.  It also improve the location info for
the nullstmts created for recovery purposes.
