Subject: Remove support for Splint static source code analyzer

Splint has not been updated since 2007 and doesn’t even build for me.
As far as I know, I'm the only person who's ever worked with Splint on
Perl 5.

Here's what changes:

* Makefile target "splint"
* Macros in XSUB.h and perl.h
* Support in regen/embed.pl
