[RFC] Make genautomata.cc output reflect insn-attr.h expectation:

[Edwin Lu]

genattr.cc currently generates insn-attr.h with the following structure:

#if CPU_UNITS_QUERY
extern int get_cpu_unit_code (const char *);
extern int cpu_unit_reservation_p (state_t, int);
#endif
extern bool insn_has_dfa_reservation_p (rtx_insn *);

however genautomata.cc generates insn-automata.cc with the following structure:
#if CPU_UNITS_QUERY
int get_cpu_unit_code (const char * ) { ... }
int cpu_unit_reservation_p (state_t, int) { ... }
bool insn_has_dfa_reservation_p (rtx_insn *) { ... }
#endif

I'm not sure if insn_has_dfa_reservation_p is supposed to be a part of the 
CPU_UNITS_QUERY conditional group or not. For consistency, I would like to 
move it outside of the group. 

This would move insn_has_dfa_reservation_p out of the #if CPU_UNITS_QUERY 
conditional inside of insn-automata.cc. This would allow us to see if the 
scheduler is trying to schedule an insn with a type which is not associated 
with a cpu unit or insn reservation through the TARGET_SCHED_VARIABLE_ISSUE 
hook.

If there is a reason for insn_has_dfa_reservation_p being within the 
conditional, please let me know!

gcc/Changelog:

        * genautomata.cc (write_automata): move endif
