Port https://reviews.llvm.org/D117354 from the MachO port. If both --symbol-ordering-file and call graph profile are present, the --symbol-ordering-file takes precedence, but the call graph profile is still used for symbols that don't appear in the order file. In addition, call graph profile described sections are now ordered before other sections.
