The previous approach of adding up the file sizes of the component sections ignored the fact that the sections did not have to be contiguous in the file. As such, it was underestimating the true size. I discovered this issue because `codesign` checks whether `__LINKEDIT` extends to the end of the file. Since we were underestimating segment sizes, this check failed. Reviewed By: #lld-macho, compnerd Differential Revision: https://reviews.llvm.org/D84574
