cxxabi_tweaks.h: Define __cxa_vec_ctor_return and _GLIBCXX_CXA_VEC_CTOR_RETURN.
* config/cpu/arm/cxxabi_tweaks.h: Define __cxa_vec_ctor_return and
_GLIBCXX_CXA_VEC_CTOR_RETURN.
* config/cpu/generic/cxxabi_tweaks.h: Ditto.
* libsupc++/cxxabi.h (__cxa_vec_ctor, __cxa_vec_cctor): Use
__cxa_vec_ctor_return.
* libsupc++/vec.cc (__cxa_vec_ctor, __cxa_vec_cctor): Ditto.
Use _GLIBCXX_CXA_VEC_CTOR_RETURN.
* g++.dg/abi/arm_cxa_vec_1.C: New test.
