[PATCH] D138456: Add new option choices for print-changed that do not output llc changes.

[Arthur Eubanks via Phabricator via llvm-commits]

if clang is giving you too much, you can always not run the backend passes with `-emit-llvm` when debugging

agreed, this is growing exponentially because it really should be multiple flags

something like
`print-changed`
`print-changed-diff[=color]`
`print-ir-pass-changed` (default true)
`print-mir-pass-changed` (default true)
`print-dotcfg`
`print-changed-verbose` (affects all change printers)
...

this will allow users to specify more than one change printer at once which I think is fine (could manually error out if not desired, but I don't think that's necessary)
