Summary: public Benchmarking our startup path has shown we spend a lot of time decoding strings (iPhone 4S / iPhone 5): * reading a 2MB JS bundle: 35ms / 15ms * decoding is to an `NSString`: 186ms / 78ms * transforming that to a `JSString`: 29ms / 10ms Instead of going through an `NSString` transformation, we generate a null-terminated bundle (0.1ms / 0.05ms to copy the data) and use `JSStringCreateWithUTF8CString` (121ms / 53ms) to generate the string. That makes decoding 70% faster. Reviewed By: javache Differential Revision: D2541140 fb-gh-sync-id: 09a016b8edfd46a9b62682c76705564d2024e75e
