llvmGen: Pass -optlo flags last to opt
LLVM, like GHC, processes flags in the order that they appear.
Consequently, we need to ensure the user-provided flags appear last so
they can override flags produced by GHC. See #14821.
Test Plan: `ghc -O2 -optlo-O2 -v3 $FILE` and ensure that `opt` and `llc`
are invoked with `-O2`.
