TI: Crash [@ js::mjit::Enter
Method JIT] or "Assertion failure: Call site vanished ."
Function("\ __defineSetter__(\"x\",Object.keys)\ (z=x instanceof.some)\ ")() crashes js opt shell on JM changeset c340841f0465 with -m, -a and -n at a weird memory location with js::mjit::EnterMethodJIT on the stack and asserts js debug shell at Assertion failure: Call site vanished.
jsop_instanceof generated an inline stub call when an operand is a known non-object, skipping the rejoin paths from the GETPROP it issues later. This changes the path so that the jsop_getprop is always emitted. http://hg.mozilla.org/projects/jaegermonkey/rev/215b6027c77d
