1.Add typelowering framework. 2.Add newobjdynrange in typelowering which brings static TS type info to runtime phase. 3.Serialize and deserialize hclass table with snapshot, fix minor bugs in snapshot by the way. 4.Add IsFormTSTypeBit in HClass to distinguish hclasses which come from compile phase. 5.Fix compatibility issues in property operations api and some builints api. 6.Add 3 compatibility issues test cases.
