4222 (mark_threaded_blocks): Remove code to truncate thread paths that
4223 cross multiple loop headers. Instead invalidate the cached loop
4224 iteration information and handle case of a thread path walking
4225 into an irreducible region.

4230 * config/rs6000/rs6000.c (rs6000_split_signbit): Change some
4231 assertions. Add support for doing the signbit if the IEEE 128-bit
4232 floating point value is in a GPR.

4234 (signbit<mode>2_dm): Delete using <Fsignbit> and just use "wa".
4235 Update the length attribute if the value is in a GPR.
4236 (signbit<mode>2_dm_<su>ext): Add combiner pattern to eliminate
4237 the sign or zero extension instruction, since the value is always 0/1.

4242 extracting SImode to a GPR register so that we can generate a
4243 store, limit the vector to be in a traditional Altivec register
4244 for the vextuwrx instruction.
