7793 – static assert( void_function() ) gives misleading error message

void f(){}
static assert(f());
----
bug.d(10): Error: cannot evaluate f() at compile time
bug.d(10): while evaluating: static assert(f())
But actually f() was successfully evaluated at compile time!

And it also applies to static if.

Fix regression introduced by issue 7793 fix.
In 3bfac13, inc is set to 2 instead of 0, which causes errors to go by unnoticed in some circumstances.
An alternative fix for 7793 would be to only skip invoking e->ctfeInterpret() if the type is not bool – I'm not sure why/if returning early is preferrable here.
