Due to inlining, descovering which specific call site to a function with
the attribute "warning" or "error" is painful.

In the IR record inlining decisions in metadata when inlining a callee
that itself contains a call to a dontcall-error or dontcall-warn fn.

Print this info so that it's clearer which call site is problematic.
