The following testcase asserts on ionmonkey revision c34398f961e7 (run with --ion -n), tested on 64 bit:


function g() {}
for(var i = 0; "0 == 0"; i++) {
    g(0 || 1);
}
The fix should reuse the logic of IonBuilder::discardCallArgs (MCallOptimize).
I recently worked on it, so I take.

Share discardCallArgs function between Inlining and Native function substitution.
