Good catch. This isn't a short story... In short words, it was to save codes in 
predefined-arch-macros.c.
If set gracemont as a series of atom processors, macros like 
`corei7`(predefined-arch-macros.c:2061-2062) won't be generated by 
`-march=gracemont`, and for history reasons, atom series processors defined 
some extra macros of their names, like "tremont", "goldmont", ... but these 
macros are not used any longer IIRC. So I decided to define gracemont as a 
non-atom series one.
