Normal Wasm load/stores currently go through a byte
reversing pipeline. Atomic load/stores however do not go
through it and as a result do not produce the correct result on
Big Endian platforms.

This CL is adding this functionality to wasm-compiler by
introducing a new macro `CASE_LOAD_STORE` which takes in an
additional input `wasm::ValueType` needed by
BuildChangeEndiannessLoad and  Store.
