Verify that macho-o delta64 relocs have the same offset. The delta64 relocation is represented as the pair ARM64_RELOC_SUBTRACTOR and ARM64_RELOC_UNSIGNED. Those should always have the same offset, so this adds a check and tests to ensure this is the case. Also updated the error printing in this case to shows both relocs when erroring on pair. llvm-svn: 255274

Parsed alignment should be a power of 2. The .o path always makes sure to store a power of 2 value in the Section alignment. However, the YAML code didn't verify this. Added verification and updated all the tests which had a 3 but meant to have 2^3. llvm-svn: 264228
