The optimization diagnostic interface.

It allows reporting when optimizations are performed and when they are not along with the reasons for it. Hotness information of the corresponding code region can be included in the remark if DiagnosticsHotnessRequested is enabled in the LLVM context.

Whether we allow for extra compile-time budget to perform more analysis to be more informative.

This is useful to enable additional missed optimizations to be reported that are normally too noisy. In this mode, we can use the extra analysis (1) to filter trivial false positives or (2) to provide more context so that non-trivial false positives can be quickly detected by the user.
