The following testcase asserts on ionmonkey revision acf3c1fb7c94 (run with --ion-eager), tested on 64 bit:
genexp = "x * x for (x in [])";
genexpParened = "(" + genexp + ")";
needParens(2, "if (1, xx) { }");
function needParens(section, pat, exp) {
ft = pat.replace(/xx/, genexpParened);
try {
f = new Function(ft);
} catch(e) { }
overParenTest(section, f, exp);
}
function overParenTest(section, f, exp) {
var uf = "" + f;
if (uf.indexOf(genexpParened) != -1) { }
}

I remember this issue being posted in a bug before, but can't seem to find it now.
JSOP_PUSH for |this| is followed by JSOP_NOTEARG so IonBuilder can be single-pass with MPassArg at point-of-definition. In adding JSOP_NOTEARG, I missed a spot that asserts the next op after JSOP_PUSH is JSOP_CALL.
