* add backticks around special type identifiers in

    tabstractprocdef.typename_paras(), after accidentally committing the
    removal of the double quotes in r34358
   o the reason for not using double quotes is that the output of this routine
     is used for some LLVM identifier names, and you can't have double quotes in
     LLVM identifiers (any other character, including space, is no problem)
