    819: Update legacy mangling of names r=philberty a=philberty
    
    In rust the mangling of names needs to handle cases such as qualified paths
    <&mut T as Deref>::deref. Assemblers cannot handle '&' and whitespace
    otherwise we will fail to assemble the functions, the legacy mangling
    scheme turns all reference's '&' into 'RF' and all whitespace into '$'
    this means we can mangle more complex canonical paths. Which are needed
    in order to support the deref operator overloading.
