Wasm2js memory fixes (#2003)

* I64ToI32Lowering - don't assume address 0 is a hardcoded location for scratch memory. Import __tempMemory__ for that.
* RemoveNonJSOps - also use __tempMemory__. Oddly here the address was a hardcoded 1024 (perhaps where the rust program put a static global?).
* Support imported ints in wasm2js, coercing them as needed.
* Add "env" import support in the tests, since now we emit imports from there.
* Make wasm2js tests split out multi-module tests using split_wast which is more robust and avoids emitting multiple outputs in one file (which makes no sense for ES6 modules)
