Summary:
`JSBigMmapString` needs to know too much about the details of the "optimized bundle" format. In honour of this fact, I'm renaming it to `JSBigOptimizedBundleString`. In a following diff, I will introduce a new class just for File-backed Strings, whose only responsibility is dealing with an mmaped region.
This diff already pulls in some fixes for formatting reference and pointer declarations from the linter.
