+Summary: We dont use shortest encoding for negative long constants
+
+Consider
+
+class T {
+	static void Main () {
+		const long a = -1;
+		System.Console.WriteLine (a);
+	}
+}
+
+We generate 
+
+        IL_0000:  ldc.i8 0xffffffffffffffff
+        IL_0009:  call void class
+[mscorlib]'System.Console'::'WriteLine'(int64)        IL_000e:  ret
+
+But it would be shorter to ldc.i4.m1 / conv.i8.
