Full C test case that doesn't require hardware like UART.

This testcase tests against the code as generated by avr-gcc-8.5 -Os. It should
work for all AVR devices including reduced tiny like ATtiny40, thus eligible
for

testsuite/gcc.target/avr/torture

Pairs that produce different results with avr-gcc v14 (current master). are:

p1,p2 = 3,6;  4,6;  5,4;  6,4  and  7,2.
