More elaborate C test case.
This is a more complicated test case, compile with
> avr-gcc -c pi-i.c -mmcu=atmega8 -Os -mcall-prologues -fno-tree-loop-optimize
> -fno-move-loop-invariants && avr-size pi-i.o
Code sizes are:
664 with avr-gcc v8.5
992 with avr-gcc v11.3
834 with avr-gcc master with the change from comment #13
So there is a clear improvement with patch #13, but size is still +25% compared
to v8. What also has an effect is -fno-split-wide-types.
The test case mostly operates on float; unfortunately I don't have a similar
test-case for 32-bit integers at hand.
