Herald added a reviewer: libc++abi.

Instead of having complicated options like LIBCXX_ENABLE_STATIC_ABI_LIBRARY
and LIBCXX_STATICALLY_LINK_ABI_IN_STATIC_LIBRARY, introduce the new
libcxxabi-objects choice of ABI library to allow merging the ABI library
objects into libc++.

Note that the same refactoring can be applied to how libc++abi merges
libunwind's objects, however that can be done as a separate step.
