[PATCH] [analyzer] Remove dead code in ObjCDeallocChecker that checked for a missing [super dealloc] call

[David Kilzer]

I did try writing a test for this, but the diag::warn_objc_missing_super_dealloc message for the check in Sema::ActOnFinishFunctionBody() is printed instead of this one.

I do not have commit access.  Please commit for me at your convenience.  Thanks!
