[patch,avr] Ad PR54222: Add bitsfx and fxbits to stdint.h

[Denis Chertykov]

2013/1/21 Georg-Johann Lay <avr@gjlay.de>:
> This adds the "Embedded C" bitsfx and fxbits functions to stdfix.h.
>
> The original stdfix.h is installed as stdfix-gcc.h and included by the new,
> avr-specific stdfix.h.
>
> The implementation uses __builtin_memcpy to get a no-op implementation.
>
> Ok for trunk?
