[lld-macho] Fix & refactor symbol size calculations I noticed two problems with the previous implementation: * N_ALT_ENTRY symbols weren't being handled correctly -- they should determine the size of the previous symbol, even though they don't cause a new section to be created * The last symbol in a section had its size calculated wrongly; the first subsection's size was used instead of the last one I decided to take the opportunity to refactor things as well, mainly to realize my observation [here](https://reviews.llvm.org/D98837#inline-931511) that we could avoid doing a binary search to match symbols with subsections. I think the resulting code is a bit simpler too.
