nice! DBC below.

test/mjsunit/regress/regress-builtinbust-1.js:9: assertThrows("a.shift()");

I guess here is the full list of breakers:

assertThrows(function() { a.shift(); }, TypeError);
assertThrows(function() { a.pop(); }, TypeError);
assertThrows(function() { a.push(5); }, TypeError);
assertThrows(function() { a.unshift(5); }, TypeError);
assertThrows(function() { a.splice(0, 1); }, TypeError);
