The SectionStr is already copied in addSection, so there is no need to copy it again in the Section constructor. Pull Request: llvm#167278

Pull Request Overview
This PR refactors the SpecialCaseList::Section class to store SectionStr as a StringRef instead of std::string. The change eliminates redundant copying since the string is already copied into the StrAlloc BumpPtrAllocator before the Section is constructed.
- Moved the
SectionStr.copy(StrAlloc)call to execute beforeSections.emplace_back()instead of after - Changed
Section::SectionStrmember type fromstd::stringtoStringRef
