PR target/83862
* config/rs6000/rs6000-protos.h (rs6000_split_signbit): Delete,
no longer used.
* config/rs6000/rs6000.c (rs6000_split_signbit): Likewise.
* config/rs6000/rs6000.md (signbit<mode>2): Change code for IEEE
128-bit to produce an UNSPEC move to get the double word with the
signbit and then a shift directly to do signbit.
(signbit<mode>2_dm): Replace old IEEE 128-bit signbit
implementation with a new version that just does either a direct
move or a regular move. Move memory interface to separate insns.
Move insns so they are next to the expander.
(signbit<mode>2_dm_mem_be): New combiner insns to combine load
with signbit move. Split big and little endian case.
(signbit<mode>2_dm_mem_le): Likewise.
(signbit<mode>2_dm_<su>ext): Delete, no longer used.
(signbit<mode>2_dm2): Likewise.
