you could insert in your irq routine the line

 asm (".global __vector_3\n\t .equ __vector_3, __vector_13");

Where __vector_13 is the main name of your irq function and __vector_3 is the alias that you are newly defining. This way, you will be avoiding the unnecessary jump.

Would it be worth it to work this up in a C macro and add it to avr-libc?

This is a fairly common question and it would be nice to have a simple solution for users.
