* Reflect instruction renaming in code (#2128)Heejin Ahn2019-05-211-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Reflected new renamed instruction names in code and tests: - `get_local` -> `local.get` - `set_local` -> `local.set` - `tee_local` -> `local.tee` - `get_global` -> `global.get` - `set_global` -> `global.set` - `current_memory` -> `memory.size` - `grow_memory` -> `memory.grow` - Removed APIs related to old instruction names in Binaryen.js and added APIs with new names if they are missing. - Renamed `typedef SortedVector LocalSet` to `SetsOfLocals` to prevent name clashes. - Resolved several TODO renaming items in wasm-binary.h: - `TableSwitch` -> `BrTable` - `I32ConvertI64` -> `I32WrapI64` - `I64STruncI32` -> `I64SExtendI32` - `I64UTruncI32` -> `I64UExtendI32` - `F32ConvertF64` -> `F32DemoteI64` - `F64ConvertF32` -> `F64PromoteF32` - Renamed `BinaryenGetFeatures` and `BinaryenSetFeatures` to `BinaryenModuleGetFeatures` and `BinaryenModuleSetFeatures` for consistency.

* wasm2js: avoid reinterprets (#2094)Alon Zakai2019-05-101-0/+181
In JS a reinterpret is especially expensive, as we implement it as a write to a temp buffer and a read using another view. This finds places where we load a value from memory, then reinterpret it later - in that case, we can load it using another view, at the cost of another load and another local. This is helpful on things like Box2D, where there are many reinterprets due to the main 2D vector class being an union over two floats/ints, and LLVM likes to do a single i64 load of them.
