perl.h - silence certain warnings on HPUX globally.

There are two warnings classes which account for a very large number of
the warnings produced when building on HPUX Itanium. We know the cause
of these warnings and we are ok with ignoring them.

One set comes from our memory wrap checks, where we end up doing a
comparison against constants in certain conditions. See the comments in
handy.h line 2723 related to PERL_MALLOC_WRAP.

The other set comes from our common "trick" of doing OO in C code with
casting. This is the foundation of how we manage SV types and how we
manage regular expression ops (regops).

If this logic really was a problem then we would have lots of test
failures and segfaults, and we do not, so we can silence them.
