Subject: [PATCH] [perl #114984] Glob.xs: Extend stack when returning

If a pattern passed to File::Glob consists of a space-separated list
of patterns, the stack will only be extended by doglob() enough for
the list returned by each subpattern.  So iterate() needs to extend
the stack before copying the list of files from an AV to the stack.

This fixes a regression introduced in 5.16.0.
