    i386: Remove CLDEMOTE for clients
    
    CLDEMOTE is not enabled on clients according to SDM. SDM only mentioned
    it will be enabled on Xeon and Atom servers, not clients. Remove them
    since Alder Lake (where it is introduced).
    
    gcc/ChangeLog:
    
            * config/i386/i386.h (PTA_ALDERLAKE): Use PTA_GOLDMONT_PLUS
            as base to remove PTA_CLDEMOTE.
            (PTA_SIERRAFOREST): Add PTA_CLDEMOTE since PTA_ALDERLAKE
            does not include that anymore.
            * doc/invoke.texi: Update texi file.
