1. What happened
Build size for Android has grown from 5.6.1 to 2017.1.0.
For the current project it is: from 26.1 to 27.2 MBs for il2cpp; and from 23.1 to 24.2 MBs for mono.
I have another project where it has grown from 50.6 to 53.8 for il2cpp and from 46.2 to 49.4 MBs for mono.

2. How we can reproduce it using the example you attached
- Build for 5.6 and 2017.0.1 and compare sizes

Expected: build size should be about the same size.
Actual it has grown by ~5%.
