[PATCH 6/9] ENABLE_CHECKING refactoring: generators

        * genautomata.c: Use CHECKING_P instead of ENABLE_CHECKING.
        * genconditions.c: Define CHECKING_P in the generated code.
        * genextract.c: Use flag_checking in insn_extract.
        * gengtype.c (main): Remove conditional compilation.
        * gengtype.h: Likewise.
