Summary:
See react_native_assert.{h,cpp}. Because of the BUCK+Android issue where NDEBUG is always defined, we use react_native_assert instead of assert to enable xplat asserts in debug/dev mode.
This migrates most of the codebase, but probably not 100%. The goal is to increase assertion coverage on Android, not to get to 100% (yet).
