Forgot to add, my first guess was actually to use OpCode.Ldtoken to
directly load MethodInfo, because I found the following snippet in
msdn online docs for OpCodes.LdToken:

   The following Emit constructor overloads can use the ldtoken opcode:

    * ILGenerator.Emit(OpCode, MethodInfo)
    * ILGenerator.Emit(OpCode, FieldInfo)
    * ILGenerator.Emit(OpCode, Type)

However, when I try and emit (OpCode.Ldtoken, MethodInfo), that causes
the ILGenerator to halt in mid-opcode, and monodis shows that last
opcode as "ldtoken" with no args..  Perhaps ILGenerator.Emit(OpCode,
MethodInfo) only works in mono 1.1.7 where OpCode == OpCode.Call* ?
