This commit updates the threads transformation for LLVM 10 where LLD has has breaking changes from LLVM 9. While previously the support here attempted to straddle multiple LLVM styles this is now removed in favor of simply supporting LLVM 10's style of output. This means that wasm-bindgen will only be compatible with recent nightlies and forward. The major change here is that the `__wasm_init_memory` function is automatically called by the `start` function. We handle that by placing the previous `start` function first, before stack/tls allocation. Other changes are to delete all the old code from pre-llvm-9. Closes rustwasm#2175
