compiler: add minsize attribute for -Oz
This matches the behavior of Clang, which uses optsize for -Os and adds minsize for -Oz. The code size change is all over the map, but using a hacked together size comparison tool I've found that there is a slight reduction in binary size overall (-1.6% with the tinygo smoke tests and -0.8% for the drivers smoke test).
