John McCall 02db245d5e Rip out the existing retroactive abstract-class usage checker,
which in a fit of zeal wanted to walk the entire translation unit,
and replace it with a new checker that walks the types of declarations
nested within the class.  Also, look into templates when doing this.

John McCall 38e5f433b2 Fix the build. Using declarations should not be considering when looking
for overridden virtual methods.

Douglas Gregor 7d8072e038 Diagnose the use of abstract types as array element types. Previously,
we were relying on checking for abstract class types when an array
type was actually used to declare a variable, parameter, etc. However,
we need to check when the construct the array for, e.g., SFINAE
purposes (see DR337). Fixes problems with Boost's is_abstract type
trait.

Eli Friedman 5dd02a0f65 Correctly calcluate abstract-ness in the case where an implicitly declared
method overrides a pure virtual method.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Anders Carlsson 7001794302 It's OK for a pure virtual function to override another pure virtual function. Fixes PR5222.

Anders Carlsson 65d5820892 Add a member lookup criteria constructor for searching for overridden virtual member functions. Use this instead of regular name lookup when checking for overriding functions so we will see declarations that would otherwise be hidden. Fixes 6902298.

Anders Carlsson b57738b09c Fix the bug that Eli noticed where we wouldn't look at function decls outside the class declaration.

Daniel Dunbar a45cf5b6b0 Rename clang to clang-cc.
Tests and drivers updated, still need to shuffle dirs.

Anders Carlsson 8f0d218598 Handle pointers to arrays of abstract types.

Anders Carlsson b5a27b460c More work on diagnosing abstract classes. We can now handle cases like
class C {
  void g(C c);

  virtual void f() = 0;
};

In this case, C is not known to be abstract when doing semantic analysis on g. This is done by recursively traversing the abstract class and checking the types of member functions.

Anders Carlsson eb0c532faa More improvements to abstract type checking. Handle arrays correctly, and make sure to check parameter types before they decay.

Anders Carlsson 0d5ca29b78 It's an error to try to allocate an abstract object using new.

Anders Carlsson 7cbd8fb6b0 Keep track of whether a class is abstract or not. This is currently only used for the __is_abstract type trait.
