There are two ways .llvmbc can be produced: * clang -c -fembed-bitcode=all (which also produces .llvmcmd) * LTO backend: ld.lld -mllvm -lto-embed-bitcode or -plugin-opt=-lto-embed-bitcode .llvmbc and .llvmcmd have the SHF_ALLOC flag, so they can be dropped by --gc-sections. This patch sets SectionKind::Metadata to drop the SHF_ALLOC flag. This is conceptually correct: the two sections are not part of the process image, so SHF_ALLOC is not appropriate. `test/LTO/X86/embed-bitcode.ll`: changed `llvm-objcopy -O binary --only-section` to `llvm-objcopy --dump-section`. `-O binary` does not dump non-SHF_ALLOC sections.
