[Bug target/19059] New: Atmel AVR Tiny13 and Tiny2313 support corrupted

["frouleau at naotek dot com" <gcc-bugzilla at gcc dot gnu dot org>]

AtTiny13 and AtTiny2313 are considered as avr4 architecture. But they do not
support all the instructions of avr4.
For example the "mul" instruction does not exist. See bellow a test case for mul.

avr-gcc -mmcu=attiny2313 test_mul.c

int main(void) {
	uint8_t a, b;
	uint16_t res;
	res = a * b;
}
