Bug ID: 7698
Summary: Prevent loading warnings.pm every eval statement

Suggested fix.
Currently, lib/Mail/SpamAssassin/Plugin/Check.pm injects 'no warnings
q(uninitialized);' in every eval statement it compiles. This executes quite a
bit of code just to to set the COP hints at eval compile time. If we move the
no warnings statement just outside of the quoted eval call, then it will set
the hints on the COP that does the quoted eval call and it will be inherited.
This should help speed up the eval calls.
Proof of concept:
perl -w -E'use warnings; no warnings q(uninitialized); eval q{package bar; my
$foo; print $foo}'
