Instead of caching start-of-line offsets, we now cache byte offsets at regular intervals. This fixes an issue where we had terrible performance on large minified JS, since that often means one very, VERY long line (with no line endings to cache). My machine was spending ~35ms per stack frame when throwing errors on some heavy minified websites, and after this patch, we now spend <1ms per stack frame.
