D153645 <https://reviews.llvm.org/D153645> added additional X-Form load/stores that can be generated for TLS accesses.
However, these added instructions have not been accounted for in lld. As a result,
lld does not know how to handle them and cannot relax initial-exec to local-exec
when the initial-exec sequence contains these additional load/stores.

This patch aims to resolve https://github.com/llvm/llvm-project/issues/64424.
