• Avoid t/recurse.t failing on earlier versions on 32 bit platforms
  (subroutines are smaller than it assumes)
  
• Count the size of padlist names in CVs (for v5.18 and later - earlier TODO)
  
• Handle PADNAMELIST/PADNAME introduced in v5.21.7
  two patches from Zefram:
  
• Add handling of children of METHOP and UNOP_AUX ops [CPAN #102911]
  
• More complete handling of padlists for XSUBs [CPAN #102909]
