  [GH #844] fix clang++ attributes, set -x c++ in cc

clang++ prints always a warning on c sources.
Move -x c++ from warnings upfront to cc, probed in auto::gcc
to be able to correctly probe for warnings and attributes.
This fixed almost all clang++ warnings, only dynoplibs
-Wno-parentheses-equality is missing for those.

  [GH #844] Probe for valid offsetof in structs (clang++)

Before we hardcoded clang++ as only compiler which does not compile
struct definitions inside a type specifier, offsetof() in datatypes.h.
Probe now for this behavior, and set HAS_COMPILER_OFFSETOF_ALIGNOF.
1 if allowed at compile-time, and undef if not and various
PARROT_ALIGN_<type> definitions are precomputed.

Also fix parrot/datatypes.h codingstd.
