This proxy will fill the role of proxying invalidation events down IR unit layers so that when a module changes we correctly invalidate function analyses. Currently this is a very coarse solution -- any change blows away the entire thing -- but the next step is to make invalidation handling more nuanced so that we can propagate specific amounts of invalidation from one layer to the next. The test is extended to place a module pass between two function pass managers each of which have preserved function analyses which get correctly invalidated by the module pass that might have changed what functions are even in the module. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195304 91177308-0d34-0410-b5e6-96231b3b80d8
