Nia Waldvogel 01723025d7 runtime (avr): fix infinite longjmp loop if stack is aligned to 256 bytes
The setjmp code sets r24 to 0 and checks if it is still 0 when it finishes.
This usually works because tinygo_longjmp stores the lower half of the stack pointer into r24.
However, r24 will be set to 0 if the stack is aligned to 256 bytes when entering the setjmp.

Manually set r24 to 1 in tinygo_longjmp to fix this issue.

Ayke van Laethem 9af535bf98 avr: add support for recover()
You can see that it works with the following command:

    tinygo run -target=simavr ./testdata/recover.go

This also gets the following tests to pass again:

    go test -run=Build -target=simavr -v

Adding support for AVR was a bit more compliated because it's also
necessary to save and restore the Y register.
