This is how array bounds checking behaves, right?  Always performed 
unless -release specified.

But it seems there's no built-in version/debug statement that lets 
library code have the same behavior.  The 'debug' condition is similar 
but it's only on in -debug builds, not in builds with specify neither 
-debug nor -release.

At run time it's possible to know what you ask for (doesn't work in D 2.x,
tan(0.9) is run in compile time, I presume):

import std.stdio: writefln;
import std.math: tan;

void main() {
    bool release_mode = true;
    try {
        int[1] a;
        int el = a[ cast(int)tan(0.9) ];
    }
    catch (Error e) {
        release_mode = false;
    }

    writefln(release_mode);
}

But you can't use it in a static if.
