[ELF] - Explicitly list supported relocations for x64 target.
The same we did for x86 earlier: list supported relocations explicitly and error out on unknown. Differential revision: https://reviews.llvm.org/D28564 git-svn-id: https://llvm.org/svn/llvm-project/lld/trunk@291751 91177308-0d34-0410-b5e6-96231b3b80d8
