Calls to Object.GetType() on value types generates incorrect code

[adrianoc]

int i = 10;
Console.WriteLine(i.GetType().Name);

generates

//int i = 10;
var lv_i_6 = new VariableDefinition(assembly.MainModule.TypeSystem.Int32);
md_TopLevelStatements_1.Body.Variables.Add(lv_i_6);
il_TopLevelMain_3.Emit(OpCodes.Ldc_I4, 10);
il_TopLevelMain_3.Emit(OpCodes.Stloc, lv_i_6);

// All good so far

//Console.WriteLine(i.GetType().Name);
// The following instruction is wrong.We should box the value instead.
il_TopLevelMain_3.Emit(OpCodes.Ldloca, lv_i_6); 

il_TopLevelMain_3.Emit(OpCodes.Callvirt, assembly.MainModule.ImportReference(TypeHelpers.ResolveMethod(typeof(System.Object), "GetType",System.Reflection.BindingFlags.Default|System.Reflection.BindingFlags.Instance|System.Reflection.BindingFlags.Public)));

correct code:

...
// All good so far

//Console.WriteLine(i.GetType().Name);
il_TopLevelMain_3.Emit(OpCodes.Ldloc, lv_i_6);  // load the integer value
il_TopLevelMain_3.Emit(OpCodes.Box, assembly.MainModule.TypeSystem.Int32);  // box

il_TopLevelMain_3.Emit(OpCodes.Callvirt, assembly.MainModule.ImportReference(TypeHelpers.ResolveMethod(typeof(System.Object), "GetType",System.Reflection.BindingFlags.Default|System.Reflection.BindingFlags.Instance|System.Reflection.BindingFlags.Public)));
