    Revert "Add purgeObj() to remove the symbol table entries for an object"
    
    This reverts commit 9e6e4796437a7fc23e83605a45db9b2663570123.
    
    I reverted it because one of these two patches
      9e6e4796437a7fc23e83605a45db9b2663570123 Add purgeObj()
      b5e8b3b162b3ff15ae6caf1afc659565365f54a8 Make the linker API thread-safe
    
    causes a seg-fault on Windows.  The seg-fault happens immediately
    the linker is invoked, in ghci or in Template Haskell.
    
    I believe that it is the "linker API thread-safe" commit that causes
    the seg-fault; it happens even if the "purgeObj" commit alone is
    reverted.  But since the two patches mess with the same code, to
    revert the "linker API" patch I had revert both.
