4494 – ICE(cod1.c) Array literal filled with results of void function

void foo() {}
void main() {
 [foo];
}
Dmd 2.047 prints:
Internal error: ..\ztc\cod1.c 2650

Changing platform to All (affects Linux too).
Similar code:
void[] p = [cast(void)42];
As of DMD-2.051, now prints:
Internal error: ../ztc/cod1.c 3057

Maybe
 if (type->nextOf()->ty == Tvoid)
 error("%s of type void[] has no value", toChars());
Is a better error message (I really am no good at writing them :)

Oops, previous patch didn't take into account that empty '[]' array literals are allowed to be void.
