Reapply "[RemoveDIs] Load into new debug info format by default in LLVM (#89799)"

Fixes the broken tests in the original commit:
  2f01fd99eb8c8ab3db9aba72c4f00e31e9e60a05

This will probably break some downstream tools that don't already handle
debug records. If your downstream code breaks as a result of this
change, the simplest fix is to convert the module in question to the old
debug format before you process it, using
`Module::convertFromNewDbgValues()`. For more information about how to
handle debug records or about what has changed, see the migration
document:
  https://llvm.org/docs/RemoveDIsDebugInfo.html
