16581 * config/rs6000/rs6000.c (rs6000_split_signbit): Change some
16582 assertions. Add support for doing the signbit if the IEEE 128-bit
16583 floating point value is in a GPR.

16586 Update the length attribute if the value is in a GPR.
16587 (signbit<mode>2_dm_<su>ext): Add combiner pattern to eliminate
16588 the sign or zero extension instruction, since the value is always 0/1.
16589 (signbit<mode>2_dm2): Delete using <Fsignbit>.
16592 * config/rs6000/vsx.md (vsx_extract_<mode>_store_p9): If we are
16593 extracting SImode to a GPR register so that we can generate a
16594 store, limit the vector to be in a traditional Altivec register
16595 for the vextuwrx instruction.
