Split c-common.c?

Before I spend time on this, I wanted to check if you consider this a good idea. Since c-common.c has grown a lot and is quite large now, I think we might split it into c-warn.c, where various warning routines would go. What do you think? Marek

Attached patch for PR71676 and PR71678. PR71676 is for AVR target that generates wrong code when switch case index is more than 16 bits. Switch case index of larger than SImode are checked for out of range before 'casesi' expand. RTL expand of casesi gets index as SImode, but index is
