__cxa_atexit_test: declare __cxa_atexit and __cxa_finalize

After updating libc++, they're no longer declared in cxxabi.h, so the
test must declare them locally.

8bd0dc5bfe

Temporarily use a return type of "int" to avoid a Clang error about
conflicting return types.

Rewrite __cxa_atexit / __cxa_finalize

Simplify:
 - Use a single memory-mapped region to hold the table of destructors.
   Double its capacity each time it is expanded.
 - Add a recompaction pass at the end of __cxa_finalize that shifts
   entries forward and uses madvise to clean pages.
