    doc: Mark more options as Undocumented/RejectNegative [PR122243]

    In reviewing the autogenerated list of remaining undocumented options
    after my first pass through the whole chapter, I found several more
    options I'd previously overlooked that should either be marked
    Undocumented, or that were missing a RejectNegative attribute where
    one was plainly appropriate.

            * c.opt (-output-pch): Mark as Undocumented, as it seems to be
            an internal option that has never been documented anyway.
            (Werror-implicit-function-declaration): Mark deprecated option
            that is not currently documented as Undocumented.
            (fconstant-string-class=): Add RejectNegative property.

            PR other/122243
            * common.opt (fbounds-check): Mark as Undocumented, expand comments
            to explain why.
            * config/frv/frv.opt (msched-lookahead=): Mark unused option as
            Undocumented.
            * config/m68k/m68k.opt (m68851): Add RejectNegative.
            * config/nvptx/nvptx.opt (minit-regs=): Mark as Undocumented.  It's
            not currently documented and seems to have been introduced as a
            stopgap to experiment with different implementation strategies.
            * config/rs6000/476.opt (mpreserve-link-stack): Mark as
Undocumented.
            It seems to be an internal option that is enabled by default on the
            cpu that can benefit from it.
