 OpenJK even with -O0 is ~2.5x times faster then -O2 -mtune=generic :)

 Anyway, just found code example from bug 83442 is useful here too, so maybe
more people can easely test if they are affected.

32bit on commit 37d43ebb28ce8be38f3d9b0805b8b14354ce786d:

 -mtune=generic 4-7ms
 -mtune=native  6-10ms
 -O0            6-10ms

32bit current git:

 -mtune=generic  197-200ms
 -mtune=native  5-8ms
