If you think emitting `.cfi_sections` is unnecessary, I am fine and happy that this is closed. (GCC already generates `.cfi_sections .debug_frame\n`, so perhaps supporting `.cfi_sections\n` is not that costly? :) Users will newer toolchain can be a bit happier - they don't need to do `#ifdef __GCC_HAVE_DWARF2_CFI_ASM`).
