[Bug rtl-optimization/38711] New: ira should not be using df-lr except at -O1.

[zadeck at naturalbridge dot com]

Ira should be using the DF-LIVE sets, which are smaller than the DF-LR sets
when they are available (typically at O2 and above).

The proper sets can be conveniently accessed using the df_get_live_[in,out]
functions which use DF-LIVE if it is available and fall back to DF-LR if it is
not.
