commit 5990c05e78946d9b4ff474df3adb354650670fcc
Author: Simon Peyton Jones <simonpj at microsoft.com>
Date:   Fri Feb 17 12:17:08 2017 +0000

    Add VarSet.anyDVarSet, allDVarSet
    
    I need these in a later commit.
    
    Also rename
      varSetAny  -->  anyVarSet
      varSetAll  -->  allVarSet
    for consistency with other functions; eg filterVarSet
