Merge from vendor branch TNF:
Importing package for p5 module PPIx-Regexp-0.008 as dependency for
scheduled update of devel/p5-Perl-Critic to 1.108.

The purpose of the PPIx-Regexp package is to parse regular expressions
in a manner similar to the way the PPI package parses Perl. This class
forms the root of the parse tree, playing a role similar to PPI::Document.
