    rts: More const correct-ness fixes
    
    In addition to more const-correctness fixes this patch fixes an
    infelicity of the previous const-correctness patch (995cf0f356) which
    left `UNTAG_CLOSURE` taking a `const StgClosure` pointer parameter
    but returning a non-const pointer. Here we restore the original type
    signature of `UNTAG_CLOSURE` and add a new function
    `UNTAG_CONST_CLOSURE` which takes and returns a const `StgClosure`
    pointer and uses that wherever possible.
    
    Test Plan: Validate on Linux, OS X and Windows
