* vector/vector.S, irq/irq_asm.S: Make sure vectors work properly
in RAM and Flash based code. The code executed for the Flash
version runs in both cases (code in Flash/code in RAM) but as it
is less efficient than the one optimized for RAM, it put it inside
ifdef. A compilation error is generated if code is linked in Flash
with the correct ifdef set...
