StackItem.GetHashCode probably shouldn't throw any Exception.

[nan01ab]

According to the C# Specification, GetHashCode() must have some properties, for example:

The GetHashCode() method should not throw exceptions.

So, StackItem.GetHasoCode probably shouldn't throw any Exception.

But in current implementation, StackItem may throw exceptions in some cases:

• CompoundType.GetHashCode throws NotSupportedException directly;
• The default implementation of StackItem.GetHashCode is to compute the HashCode of GetSpan, but GetSpan throw an InvalidCastException in default.

Where in the software does this update applies to?

• VM
