S_process_special_blocks() should use a new stack for BEGIN blocks.

In blead at least, one of the dependencies, List​::MoreUtils, fails testing​:

t/xs/Functions.t ........ 161/? perl5.23.8​: MoreUtils.xs​:900​: XS_List__MoreUtils_after​: Assertion `tmpXSoff >= 0' failed.
t/xs/Functions.t ........ All 173 subtests passed

ok 172
ok 173
perl5.23.8​: MoreUtils.xs​:900​: XS_List__MoreUtils_after​: Assertion `tmpXSoff >= 0' failed.
Aborted

This appears to have been reported in 2012 as https://rt.cpan.org/Ticket/Display.html?id=75727 (though it didn't assert then)

Earlier this week I installed a patched List-Utils on blead and managed to reproduce the problem, and valgrind found what looked like a stack handling issue in Params​::Validate (a missing SPAGAIN).

There seemed to be other issues left after that, but I can no longer get App​::JobLog to fail even with the CPAN Params​::Validate.

Fix was applied to Params​::Validate in release 1.23. Closing!
