It works for .debug_info, which is one of the biggest sections; it does not work for .debug_line, though, which is not that big as .debug_info, but potentially might become problematic in the (distant) future; it also does not work for .debug_abbrev, .debug_addr, .debug_ranges, and some others, which are usually not that big. However, the patch should be extended to support .debug_str, which can be even larger than .debug_info.

We either mark `InputFile` or `InputSectionBase` referenced by a 64-bit absolute relocation. I prefer `InputBaseBase` which is more direct (we have spare bits in SectionBase after `keepUnique`)
