Currently only supports simple copying, other operations to follow. Reviewers: sbc100, alexshap, jhenderson Differential Revision: https://reviews.llvm.org/D70930 This is a reland of a928d127a with a one-line fix to ensure that the wasm version number is written as little-endian (it's the only field in all of the binary format that's not a single byte or an LEB, but we may have to watch out more when we start handling the linking section).
