// specific ELF sections like .Mips.options. Specific records should subclass
// MipsOptionRecord and provide an implementation to EmitMipsOptionRecord which
// basically just dumps the information into an ELF section. More information
// about .Mips.option can be found in the SysV ABI and the 64-bit ELF Object
// specification.
