This commit refines the handling of deprecation warnings for the Transactional Memory Extensions (TME) on AArch64. Instead of relying on string parsing, the compiler now inspects the parsed feature flags from aarch64_parse_extension. This ensures that warnings are correctly issued when +tme is enabled via target attributes or pragmas, addressing issues missed by the previous string-based approach. Command-line handling of +tme remains unchanged.
