Again, if the linker does not support -mllvm then -Wl,-mllvm will fail  
anyway ;).

I'm fine with current state :)

I do not prefer separate new -mllvm option for the linker.

This is a debugging aid for llvm hacker that helps him investigate  
code generation/optimization bugs. If the user does not know what he  
is debugging (lto or no-lto) then all bets are off!

If the user wants llvm code generator to print useful info to find out  
what went wrong, when LTO is ON, then you really want the linker to  
accept this command or reject. You do not want to let compiler driver  
eat this silently and not ask LTO to produce any output, which may  
mislead the user.
