When checking for abstract types, don't crash when we have a
...
FunctionProtoTypeLoc with NULL function parameter types, which can
occur in invalid code. Fixes PR9247 / <rdar://problem/9037911>.

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.

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.

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).

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.
