  commit b4dd66232df8f0d1c00796970dec7fc37fbe9edf

      Remove dead code from Perl_gv_stashpvn().

      GvHV() and HvNAME() will both always already be set, as gv_fetchpvn_flags()
      will initialise these as it walks the string in its initial loop to locate the  
      correct stash, then return early because name == name_end.

      This code has been dead since it was added in 5.000.
