  Log Message:
  -----------
  [RISCV] emit .option directive for functions with target features which differ from module default

When function has different attributes from module, emit the .option <attribute> before the function body.  This allows non-integrated assemblers to properly assemble the functions (which may contain instructions dependent on the extra target features).
