All pseudos got 0 available hard regs and therefore spills.  Something wrong
with calculation of number of available hard regs for targets which can use reg
pairs starting only on even/odd hard regs.

The fix will need changes in very sensitive part of IRA code and need some time
to write it, test, and benchmark it.  I hope it will be done at the end of
week.

Sorry for the inconvenience.
