[COFF] [X86] Don't use llvm_unreachable for unsupported relocation types This can happen if assembling a reference to _GLOBAL_OFFSET_TABLE_. While it doesn't make sense to try to assemble that for COFF, the fact that we previously used llvm_unreachable meant that the code had undefined behaviour if something tried to assemble that. The configure script of libgmp would try to assemble such a snippet (which should signal a failure). If llvm is built without assertions, the undefined behaviour meant a (near) infinite loop.
