[perl #49972] Error message for misspelled sub name in PIR code is confusing

In r27351 I've added code to PCT to check for non-existent subs and
throw an exception at the point of the call.  So, the problem is
"solved" for PCT-based languages, at least.

It still doesn't help with the case of non-existent sub names in PIR,
though, for which I recommend something along the lines of the patch
described by chromatic in
http://groups.google.com/group/perl.perl6.internals/msg/73433bac364e0bd0
.  When/if that patch is implemented we can remove the duplicate code
out of PCT.
