InvalidProgramException in .NET 7 Android application #2799
Description

With a dotnet/linker diff of: 04c49c9...b9c9da2
A unit test using HTTP fails with:
System.Net.WebException : net_webclient
----> System.InvalidProgramException : Invalid IL code in System.Net.HttpWebRequest:AddCacheControlHeaders (System.Net.Http.HttpRequestMessage): IL_0202: unused5

at System.Net.WebClient.DownloadBitsAsync(WebRequest , Stream , AsyncOperation , Action`3 )
It fails regardless if AOT is used.
ILSpy shows that IL_0202 might be after this method entirely?
