Helper that updates FunctionPropertiesInfo after inlining.

== Synopsis

Declared in `<llvm/Analysis/FunctionPropertiesAnalysis.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
class FunctionPropertiesUpdater;
----

== Description

A FunctionPropertiesUpdater keeps the state necessary for tracking the changes llvm::InlineFunction makes. The idea is that inlining will at most modify a few BBs of the Caller (maybe the entry BB and definitely the callsite BB) and potentially affect exception handling BBs in the case of invoke inlining.
