Eliminate POSIX::int_macro_int, and all the complex AUTOLOAD fandango

that creates closures round it. Instead, wrap WEXITSTATUS, WIFEXITED,
WIFSIGNALED, WIFSTOPPED, WSTOPSIG and WTERMSIG directly with XS.
The shared library is slightly larger, but dynamic memory usage savings
beat this, even within one thread of one process. Simpler code too.

-=head2 investigate removing int_macro_int from POSIX.xs
-
-As a hang over from the original C<constant> implementation, F<POSIX.xs>
-contains a function C<int_macro_int> which in conjunction with C<AUTOLOAD> is
-used to wrap the C functions C<WEXITSTATUS>, C<WIFEXITED>, C<WIFSIGNALED>,
-C<WIFSTOPPED>, C<WSTOPSIG> and C<WTERMSIG>. It's probably worth replacing
-this complexity with 5 simple direct wrappings of those 5 functions.
-
-However, it would be interesting if someone could measure the memory usage
-before and after, both for the case of C<use POSIX();> and the case of
-actually calling the Perl space functions.
