Thanks for the explanation. I agree that there's value in having the program header count extension in the parsing and dumping code.

In addition to removing the lld changes, I think this change warrants being split into at leasr two PRs, one (or more) which does the refactoring (if needed) such that both extended program headers and section headers can be handled all together and another that actually implements the program header functionality. You will also probably want a separate change specifically for llvm-objcopy, so that it can write objects containing many program headers.
