This patch adds support for the atomic_abi attribute, specifid in https://github.com/riscv-non-isa/riscv-elf-psabi-doc/blob/master/riscv-elf.adoc#tag_riscv_atomic_abi-14-uleb128version. This was previously reverted due to ld.bfd segfaulting w/ unknown riscv attributes. Attribute emission is now guarded by a backend flag `--riscv-abi-attributes`, which is off by default. Linker support in LLD for attribute merging is now in a standalone patch. Reviewers: kito-cheng, MaskRay, asb Reviewed By: MaskRay Pull Request: https://github.com/llvm/llvm-project/pull/90266
