    Restore documentation for const/volatile functions [PR107942]

    In r5-7698-g8648c55f3b703a I accidentally removed the documentation of
    GCC's special interpretation of const/volatile qualifiers on functions
    from the function attributes section, thinking this was just a
    bit-rotten leftover from old versions of GCC.  PR107942 points out
    that this functionality is still present even though the docs are now gone.

    I decided this material didn't really belong in the function
    attributes discussion, but a new subsection in the general list of GCC
    extensions to the C language.  And I agree with the comment in the
    issue that we shouldn't really recommend this usage any more.
