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.
