We also need to save these registers in the .Lslow path of
sysdeps/x86_64/dl-tlsdesc.S's _dl_tlsdesc_dynamic, as well as in the two
other entry points that save and restore registers:
_dl_tlsdesc_resolve_rela and _dl_tlsdesc_resolve_hold. Would you please
fix those too, if we're changing dl-trampoline.S to this effect?
