[Regexp] Incorrect match result for Regexp including unicode property

Bug #20615: [Regexp] Incorrect match result for Regexp including unicode property

Description

A regex pattern including an unicode property is not matched correctly.

/\A *\z/.match?('') # => true
/\Ap{White_Space}*\z/.match?('') # => false

I think both of these patterns should be matched but the later pattern including an unicode property is not.

This regexp pattern is invalid.
Sorry for my mistake.
