Address review comments:
1. Renamed the attribute to "not_tail_called".
I chose "not_tail_called" over "notailcall" or "notail" to better distinguish it from the attribute that is proposed in http://reviews.llvm.org/D12547 (which is tentatively named "disable_tail_calls").
2. Made changes to error-out if a virtual function or an objective-c method is marked "not_tail_called".
I made this change because this attribute isn't useful when the compiler cannot resolve the function call statically at compile time and it isn't important for the use case I have.
3. Added code examples to AttrDocs.td.
