Change $SIG{__WARN__} and $SIG{__DIE__} to magic subs

ABSTRACT

It sounds really stoopid to say $SIG{__WARN__} on a machine which doesn't have signals.

DESCRIPTION

Perl 6 is going to be portable to all kinds of system, just like Perl 5. Some of those systems won't have signals, so it's time to question why the warn and die hooks are implemented as signal handlers.

Instead, let's implement them as magic subroutines WARN and DIE like BEGIN and END. This seems more consistent anyway. Well, to me.

IMPLEMENTATION

Call subroutines WARN and DIE instead of the signal handler versions. Everything else stays the same.
