描述
Use System.Reflection.Metadata to emit the following:
- A module with exactly 0xFFFF methods
- The last type in the module has no methods
This will hit a corner case in the ECMA-335 spec where the TypeDef record for the last type should end up with a MethodList value of 0x10000, but per the spec, the MethodList column is only 2 bytes wide (because the method count fits in 2 bytes), making the value fall out of range.
This also affects other similar columns, such as TypeDef.FieldList, and MethodDef.ParamList.
Per the spec, null might be a legal value to put there in that case.
