[RS6000] power8 unaligned fp load/store
According to the POWER8 Processor User’s Manual and some
experimentation on power8 hardware, unaligned fp load/store on power8
does not invoke the alignment interrupt.
* config/rs6000/rs6000.h (SLOW_UNALIGNED_ACCESS): Make scalar
float access depend on TARGET_EFFICIENT_UNALIGNED_VSX.
* config/rs6000/rs6000.opt (-mefficient-unaligned-vsx): Renamed
from -mefficient-unaligned-vector. Note that this affects fp too.
