  [RemoveDIs] Don't convert debug-info in bitcode-loading just now (#80865)

We've been building and testing this no-debug-intrinsic work inside of
the pass manager for a while, so that optimisation passes get exercised
and tested when we turn it on. However, by converting to the
non-intrinsic form in the bitcode loader, we accidentally caused all
parts of LLVM to potentially see non-intrinsic debug-info.

Seeing how we're trying to turn things on incrementally, it was a
mistake to go this far this fast: we can instead just focus on enabling
during optimisations for the moment, then all the other parts of LLVM
later.
