[kernels] boolean scalar equality operators

EwBinarySca was missing the implementation for boolean equality
operators, meaning that simple equality checks for control flow using
booleans was not working.

Adds a testcase.

Previous error:
RewriteToCallKernelOpPass failed with the following message [ no kernel
for operation `ewEq` available for the required input types `(i1, i1)`
and output types `(i1)`

A = rand(1,1, 0.0, 1.0, 1.0, -1);
x = as.scalar<f64>(A[0,0]);

terminate = false;
while (terminate == false) {
    if (x > 0.5) {
        terminate = true;
    }
    x = x + 0.5;
}
print("done.");
