With this, libclang_rt.profile_osx.a can be linked, that is coverage and PGO-instrumented builds should now work with lld. section$start and section$end symbols can create non-existing sections. They're also undefined symbols that are only magic if there isn't a regular symbol with their name, which means the need to be handled in treatUndefined() instead of just looping over all existing sections and adding start and end symbols like the ELF port does. To represent the actual symbols, this uses absolute symbols that get their value updated once an output section is layed out. segment$start and segment$end are still missing for now, but they produce a nicer error message after this patch. Main part of PR50760. Differential Revision: https://reviews.llvm.org/D106629
