Bug 1518753 part 5 - Stop using JSProtoKey for initial shapes. r=tcampbell I added this optimization in bug 1299107 to share more shapes across compartments. Unfortunately this doesn't play well with same-compartment realms (ICs can misbehave) because it relies on compartments being isolated from each other. I think we should remove this optimization: * Fixing the IC issue is impossible without deoptimizing everything. * I added it mainly for chrome globals. The shared-JSM-global work has eliminated the need for this there. * Same-compartment realms win memory back by eliminating CCWs etc. * It's quite a lot of complicated code.
