Add source map support of WasmModule This CL adds a new class WasmModuleSourceMap for source map support of WasmModule, which maps C/C++ source code to WASM bytecode. Via this support, V8 can build a direct map of source code and JITted code and inform profilers of it, thus the source-code-level profiling information is presented.
