[mac/lld] Fix scale computation for vector ops in PAGEOFF12 relocations With this, llvm-tblgen no longer tries and fails to allocate 7953 petabyte when it runs during the build. Instead, `check-llvm` with lld/mac as host linker now completes without any failures on an m1 mac. This vector op handling code matches what happens in: - ld64's OutputFile::applyFixUps() in OutputFile.cpp for kindStoreARM64PageOff12 - lld.ld64.darwinold's offset12KindFromInstruction() in lld/lib/ReaderWriter/MachO/ArchHandler_arm64.cpp for offset12scale16 - RuntimeDyld's decodeAddend() in llvm/lib/ExecutionEngine/RuntimeDyld/Targets/RuntimeDyldMachOAArch64.h for ARM64_RELOC_PAGEOFF12 Fixes PR49444.
