.NET Decompiler with support for PDB generation, ReadyToRun, Metadata (&more) - cross-platform!

Siegfried Pammer 1f4fd68b3f Make optional AST slots nullable Optional single-child slots return T? with a real null instead of a role null-object, taking the C# grammar as the oracle for which slots are optional. The generator emits the property type as T? and matches it with MatchOptional, and consumers move from .IsNull to is null / ?.. This covers the optional statement, member, try-catch, creation-initializer and pattern slots and the optional NameSlot tokens. A few slots the grammar marks required but the decompiler legitimately leaves empty (the implicit-element-access target, an implicitly-typed lambda parameter's type) are flipped to nullable as well.
