Summary:
Changelog: [internal]
If value returned from `vImageBoxConvolve_ARGB8888` is negative, an error occurred.
Converting a negative number to `unsigned long` produces a large positive number (larger than memory). Trying to allocate that much memory fails, malloc returns NULL, and abort triggered inside `RCTBlurredImageWithRadius`.
To fix this we need to check for return value from `vImageBoxConvolve_ARGB8888`.
