Side note: CallInst without debug locations are particularly problematic.
If:
* you have a call inst with no location
* in a function with debug info
* calling another function with debug info
* and you inline that call site
<badness> (assertion failures and if not that, then weirdly broken debug
info where the inline scope is never created, etc)
