* config/rs6000/predicates.md (const_0_to_7_operand): New
predicate, recognize 0..7.
* config/rs6000/rs6000.c (rs6000_expand_vector_extract): Add
support for doing extracts from V16QImode, V8HImode, V4SImode
under ISA 3.0.
* config/rs6000/vsx.md (VSX_EXTRACT_I): Mode iterator for ISA 3.0
vector extract support.
(VSX_EXTRACT_PREDICATE): Mode attribute to validate element number
for ISA 3.0 vector extract.
(VSX_EX): Constraints to use for ISA 3.0 vector extract.
(vsx_extract_<mode>, VSX_EXTRACT_I): Add support for doing
extracts of a constant element number from small integer vectors
on 64-bit ISA 3.0 systems.
(vsx_extract_<mode>_di): Likewise.
* config/rs6000/rs6000.h (TARGET_VEXTRACTUB): New target macro to
say when we can do ISA 3.0 vector extracts.
* config/rs6000/rs6000.md (stfiwx): Allow DImode in Altivec
