  [AVR] Fix incorrect calling convention for varargs functions

An i8 argument should only cost 1 byte on the stack. This is
compatible with avr-gcc.

There are also more test cases (of calling convention) are added.

  Log Message:
  -----------
  [AVR] Generate 'rcall' instead of 'call' on avr2 and avr25

The 'call' (long call) instruction is available on avr3 and above,
and devices in avr2 and avr25 should use the 'rcall' (short call)
instruction for function calls.
