PrintIL options to output op-codes in the format directly copyable to AssertOpCodes method

[dadhi]

For example, in #398 test instead of default format:

<Test_switch_for_all_integer_types_with_cases_starting_from_0>
IL_0000: ldarg.1
IL_0001: stloc.0
IL_0002: ldloc.0
IL_0003: switch (IL_0041, IL_0047, IL_0077, IL_0053, IL_0059, IL_0065, IL_0071)
IL_0036: br IL_0077
IL_0041: ldc.i4.0
IL_0042: br IL_0078
IL_0047: ldc.i4.1
IL_0048: br IL_0078
IL_0053: ldc.i4.3
IL_0054: br IL_0078
IL_0059: ldc.i4.4
IL_0060: br IL_0078
IL_0065: ldc.i4.5
IL_0066: br IL_0078
IL_0071: ldc.i4.6
IL_0072: br IL_0078
IL_0077: ldc.i4.m1
IL_0078: ret
</Test_switch_for_all_integer_types_with_cases_starting_from_0>

I want an option to output that can be directly used in AssertOpCodes (possibly including the comments):

        fs.AssertOpCodes(
            OpCodes.Ldarg_1,
            OpCodes.Stloc_0,
            OpCodes.Ldloc_0,
            OpCodes.Switch, // (IL_0041, IL_0047, IL_0077, IL_0053, IL_0059, IL_0065, IL_0071),
            OpCodes.Br,
            OpCodes.Ldc_I4_0,
            OpCodes.Br,
            OpCodes.Ldc_I4_1,
            OpCodes.Br,
            OpCodes.Ldc_I4_3,
            OpCodes.Br,
            OpCodes.Ldc_I4_4,
            OpCodes.Br,
            OpCodes.Ldc_I4_5,
            OpCodes.Br,
            OpCodes.Ldc_I4_6,
            OpCodes.Br,
            OpCodes.Ldc_I4_M1,
            OpCodes.Ret
        );
