Allow illegal custom modifiers on generic constraints
Roslyn decided to do a breaking change to the ECMA-335 file format by generating an illegal custom modifier for the `unmanaged` constraint. The purpose of the modifier is to poison such types for old versions of the C# compiler (the modifier otherwise isn't necessary for the feature to work). This also poisons a lot of the .NET ecosystem too (breaking everything ranging from Mono to the C++/CLI compiler).
We need to update our stack to support this and unblock our customers.
