and other functions.

When these functions return null, the pointer is not freed by
them/ownership is not transfered. So we should allow the user to free
the pointer by calling another function when the return value is NULL.

These are CallEvent-equivalents of helpers already accessible in
CheckerContext, as part of making it easier for new checkers to be written
using CallEvent rather than raw CallExprs.

Also, Decls already carry a pointer to the ASTContext, so there's no need
to pass an extra argument to the predicate.

Add FIXMEs for the traits visible from multiple translation units.
Currently the macros hide their key types in an anonymous namespace.

Also, move the REGISTER_*_WITH_PROGRAMSTATE macros to ProgramStateTrait.h.

This doesn't get rid of /all/ explicit uses of ProgramStatePartialTrait,
but it does get a lot of them.

The ImmutableMap should not be the key into the GDM map as there could
be several entries with the same map type. Thanks, Jordan.

This complicates the usage of the macro a bit. When we want to retrieve
the whole map, we need to use another name. Currently, I set it to be
Name ## Ty as in "type of the map we are storing in the ProgramState".

This is a syntactic checker aimed at helping iOS programmers correctly
subclass and override the methods of UIViewController. While this should
eventually be covered by the 'objc_requires_super' attribute, this
checker can be used with the existing iOS SDKs without any header changes.

This new checker is currently named 'alpha.osx.cocoa.MissingSuperCall'.

there is no error.
