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&.

This ought to fix PR11926, a crash when when running Clang built with GCC 4.7

g++4.7, which reuses stack space allocated for temporaries. CFGElement::getAs
returns a suitably-cast version of 'this'. Patch by Markus Trippelsdorf!

No test: this code has the same observable behavior as the old code when built
with most compilers, and the tests were already failing when built with a
compiler for which this produced a broken binary.

        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

llvm-svn: 155756

This is just papering over a major bug in isPODType, real fix coming up soon.

Keep the old definition for C++98 so we don't break tr1::is_pod.

This time, also fix the caller of AddGlue to properly handle
incomplete chains. AddGlue had failure modes, but shamefully hid them
from its caller. It's luck ran out.
