@clayborg requested <https://reviews.llvm.org/D51578#1383458> more effective loading of concatenated sections. For compressed sections it means one has to measure decompressed size of both to be able to effectively allocate memory for both of them. But current `LoadSectionData()` can only load the data without knowing first how big it will be. Therefore D51578 <https://reviews.llvm.org/D51578> introduces `SectionReader` but it needs to also handle subranges of DWP `Section`. Despite DWP `Section` is not supported to be compressed and compressed sections do not need to support subranges to unify the API I had to replace `Section *` by `SectionPart` for all the cases.
