Andreas Haas 53af0d1ad3 [wasm] Alignment information of wasm programs cannot be trusted 
This CL removes code which is based on the assumption that if
WebAssembly code says that memory accesses are aligned, that they are
really aligned. On arm, memory accesses crashed when this assumption
was violated.

Most likely this CL will cause a performance regression on arm. At the
moment we plan to fix this regression eventually by using arm NEON
instructions in V8.
