#659 Better diagnostic messages for function pointer casts

[Benedikt Freisen]

Implicit and perhaps even explicit casts from function pointer types to object pointer types during array initialization should ideally produce a warning message.

There apparently are more cases where the warning (most ports) / error (for large model on stm8) is missing. I just tried to compile

extern void *p;

void f(void)
{
    p = &f;
}

void *p = &f;

void (*fp)(void);

void g(void)
{
    p = fp;
}

Out of the three, p = fp is the only one on which I get the expected warning / error.

This still applies as of [r16497], and might be related to [bugs:#3952].
