Jakob Hellermann	3c062bad0c	Fix anonymous-type lambda early-return emitting unresolvable cast (#3752 ) * Fix anonymous-type lambda early-return emitting unresolvable cast When a lambda's inferred return type contains an anonymous type and one branch returns null, the decompiler emitted an explicit cast such as `return (IEnumerable<<>f__AnonymousType0<int>>)null;`, which is invalid C#. Skip the cast in IsPossibleLossOfTypeInformation for null literals whenever the expected type contains an anonymous type: null is implicitly convertible to any reference type, so no cast is needed, and the anonymous type has no nameable form to cast to anyway.

Fix anonymous-type lambda early-return emitting unresolvable cast (#3752 )

* Fix anonymous-type lambda early-return emitting unresolvable cast

When a lambda's inferred return type contains an anonymous type and one
branch returns null, the decompiler emitted an explicit cast such as
`return (IEnumerable<<>f__AnonymousType0<int>>)null;`, which is invalid C#.

Skip the cast in IsPossibleLossOfTypeInformation for null literals whenever
the expected type contains an anonymous type:
null is implicitly convertible to any reference type, so no cast is needed,
and the anonymous type has no nameable form to cast to anyway.

Fixes #3751
