File::HomeDir => CPAN::Reporter. So my smoker is now broken.

Guilt overwhelmed me and I delayed my appointment. Pushed a revert just now.

Revert "fix [perl #76546] regex engine slowdown bug"

This reverts commit dee29c6b5bec1d6e7fccc971e31113a5d7cee844.

$ perl5.16.0 -e 'warn "t/bin/good.pl syntax OK\n" =~ /syntax OK\s+\z/si'
1 at -e line 1.
$ bleadperl -e 'warn "t/bin/good.pl syntax OK\n" =~ /syntax OK\s+\z/si'
Warning: something's wrong at -e line 1.

Will fix properly later.
