It seems that __ctfe is treated as constant in the backend.

-O).
void main()
{
import std.stdio;
if (__ctfe)
writeln("foo");
}
int main() { return __ctfe ? 1 : 0; }
__ctfe is passed to the backend as 'false', and even with -O the basic
optimizations will strip it as dead code. So it is removed after semantic
checking, but that doesn't help as semantic checking includes @nogc
checking.
