Renaming for some Emscripten EH functions has so far been done in wasm-emscripten-finalize tool in Binaryen. But recently we decided to make a compilation/linking path that does not rely on wasm-emscripten-finalize for modifications, so here we move that functionality to LLVM. Invoke wrappers are generated in LowerEmscriptenEHSjLj pass, but final wasm types are not available in the IR pass, we need to rename them at the end of the pipeline. This patch also removes uses of `emscripten_longjmp_jmpbuf` in LowerEmscriptenEHSjLj pass, replacing that with `emscripten_longjmp`. `emscripten_longjmp_jmpbuf` is lowered to `emscripten_longjmp`, but previously we generated calls to `emscripten_longjmp_jmpbuf` in LowerEmscriptenEHSjLj pass because it takes `jmp_buf*` instead of `i32`. But we were able use `ptrtoint` to make it use `emscripten_longjmp` directly here.
