Use llvm.compiler.used insetad of llvm.used
The #[used] attribute explicitly only requires symbols to be retained in object files, but allows the linker to drop them if dead. This corresponds to llvm.compiler.used semantics. The motivation to change this *now* is that https://reviews.llvm.org/D97448 starts emitting #[used] symbols into unique sections with SHF_GNU_RETAIN flag. This triggers a bug in some version of gold, resulting in the ARGV_INIT_ARRAY symbol part of the .init_array section to be incorrectly placed.
