f23bf7432c
defines a protocol that all subclasses will implement. StackFrame is currently the only subclass and the methods that Frame vends are nearly identical to StackFrame's old methods. Update all callers to use Frame*/Frame& instead of pointers to StackFrames. This is almost entirely a mechanical change that touches a lot of the code base so I'm committing it alone. No new functionality is added with this patch, no new subclasses of Frame exist yet. I'll probably need to tweak some of the separation, possibly moving some of StackFrame's methods up in to Frame, but this is a good starting point. <rdar://problem/15314068> llvm-svn: 193907
