[OpenCL] Restrict various keywords in OpenCL C++ mode
Restrict the following keywords in the OpenCL C++ language mode,
according to Sections 2.2 & 2.9 of the OpenCL C++ 1.0 Specification.
- dynamic_cast
- typeid
- register (already restricted in OpenCL C, update the diagnostic)
- thread_local
- exceptions (try/catch/throw)
- access qualifiers read_only, write_only, read_write
Support the `__global`, `__local`, `__constant`, `__private`, and
`__generic` keywords in OpenCL C++. Leave the unprefixed address
space qualifiers such as global available, i.e., do not mark them as
reserved keywords in OpenCL C++. libclcxx provides explicit address
space pointer classes such as `global_ptr` and `global<T>` that are
implemented using the `__`-prefixed qualifiers.
