Apparently we weren't checking default arguments when they were instantiated.
This adds the check, fixes the lack of instantiation caching (which seems like
it was mostly implemented but just missed the last step), and avoids
implementing non-dependent default args (for non-dependent parameter types) as
uninstantiated default arguments (so that we don't warn once for every
instantiation when it's not instantiation dependent).

filter_decl_iterator had a weird mismatch where both op* and op-> returned T*
making it difficult to generalize this filtering behavior into a reusable
library of any kind.

This change errs on the side of value, making op-> return T* and op* return
T&.

        i32 __builtin_annotation(i32, string);

Applying it to i64 (e.g., long long) generates the following IR.

        trunc i64 {{.*}} to i32
        call i32 @llvm.annotation.i32
        zext i32 {{.*}} to i64

The redundant truncation and extension make the result difficult to use.

This patch makes __builtin_annotation() generic.

        type __builtin_annotation(type, string);

For the i64 example, it simplifies the generated IR to:

        call i64 @llvm.annotation.i64

Rename isPODType (using the C++98 rules) into isCXX98PODType and make isPODType decide which one to use based on LangOptions.

- -Wc++98-compat depends on the c++98 definition
- Now __is_pod returns the right thing in c++11 and c++98 mode
- All changes to the type traits test are validated against g++ 4.7

Set the source location for the "member reference base type ... is not a

If we're giving this diagnostic because of a typo'd '.' in place of a ';' at
the end of a line, the caret previously pointed at the identifier on the
following line, which isn't as helpful as it could be. Pointing the caret at
the '.' makes it more obvious what the problem is.
