All 4 tests presented here ICE in reload pass too with `unable to find a register to spill in class =E2=80=98DIREG=E2=80=99`. I think I could fix it in LRA as it has a code for hard reg live range splitting but I think we should fix the reason (first change in GCC code) resulted in the ICE as all other targets use reload and they might have the same bug.
