bug 1262210 NEW:: Creating objects without properties is slower than creating objects with properties
- according to the MIR graphs, the code flow looks sane. Found out the issue only occurs when it compilation thread turned off, which leads a very slow but correct result.
- close to the root cause; doing more experiments and asking for consultanting
- need to take a look at the reason of generating two copies of MIR
