Refactor and optimize register allocator and live set computations - #1288

Modify 'BlockFileStreamDriver.Dispose' so that it calls Dispose(true), then calls GC.SuppressFinalize on the current object instance ('this' or 'Me' in Visual Basic), and then returns (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1063)

Provide an overridable implementation of Dispose(bool) on 'BlockFileStreamDriver' or mark the type as sealed. A call to Dispose(false) should only clean up native resources. A call to Dispose(true) should clean up both managed and native resources. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1063)

get_AllTypes creates an exception of type InvalidOperationCompilerException, an exception type that should not be raised in a property. If this exception instance might be raised, use a different exception type, convert this property into a method, or change this property's logic so that it no longer raises an exception. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1065)

get_CorLib creates an exception of type AssemblyLoadException, an exception type that should not be raised in a property. If this exception instance might be raised, use a different exception type, convert this property into a method, or change this property's logic so that it no longer raises an exception. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1065)

GetHashCode creates an exception of type InvalidOperationCompilerException, an exception type that should not be raised in this type of method. If this exception instance might be raised, either use a different exception type or change this method's logic so that it no longer raises an exception. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1065)

get_SetterMethod creates an exception of type InvalidOperationCompilerException, an exception type that should not be raised in a property. If this exception instance might be raised, use a different exception type, convert this property into a method, or change this property's logic so that it no longer raises an exception. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1065)

get_GetterMethod creates an exception of type InvalidOperationCompilerException, an exception type that should not be raised in a property. If this exception instance might be raised, use a different exception type, convert this property into a method, or change this property's logic so that it no longer raises an exception. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1065)

Provide an overridable implementation of Dispose(bool) on 'MutatorBase' or mark the type as sealed. A call to Dispose(false) should only clean up native resources. A call to Dispose(true) should clean up both managed and native resources. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1063)

Ensure that 'MutatorBase.Dispose' is declared as public and sealed (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1063)
