[SemaCXX] Unconfuse Clang when std::align_val_t is unscoped in C++03linaro-local/ci/tcwg_kernel/llvm-master-arm-next-defconfiglinaro-local/ci/tcwg_kernel/llvm-master-arm-mainline-allyesconfiglinaro-local/ci/tcwg_kernel/llvm-master-aarch64-stable-defconfiglinaro-local/ci/tcwg_kernel/llvm-master-aarch64-lts-allyesconfiglinaro-local/ci/tcwg_kernel/llvm-master-aarch64-lts-allnoconfig

When -faligned-allocation is specified in C++03 libc++ defines
std::align_val_t as an unscoped enumeration type (because Clang didn't
provide scoped enumerations as an extension until 8.0).
Unfortunately Clang confuses the `align_val_t` overloads of delete with
the sized deallocation overloads which aren't enabled. This caused Clang
to call the aligned deallocation function as if it were the sized
deallocation overload.

For example: https://godbolt.org/z/xXJELh

This patch fixes the confusion.
