Teresa Johnson f9ca75f19b [Inliner] Inlining should honor nobuiltin attributes 
Summary:
Final patch in series to fix inlining between functions with different
nobuiltin attributes/options, which was specifically an issue in LTO.
See discussion on D61634 for background.

The prior patch in this series (D67923) enabled per-Function TLI
construction that identified the nobuiltin attributes.

Here I have allowed inlining to proceed if the callee's nobuiltins are a
subset of the caller's nobuiltins, but not in the reverse case, which
should be conservatively correct. This is controlled by a new option,
-inline-caller-superset-nobuiltin, which is enabled by default.
