* config/rs6000/constraints.md (wD constraint): New constraint to
match the constant integer to get the top DImode/DFmode out of a
vector in a VSX register.
* config/rs6000/predicates.md (vsx_scalar_64bit): New predicate to
match the constant integer to get the top DImode/DFmode out of a
vector in a VSX register.
* config/rs6000/rs6000-builtins.def (VBPERMQ): Add vbpermq builtin
for ISA 2.07.
* config/rs6000/rs6000-c.c (altivec_overloaded_builtins): Add
vbpermq builtins.
* config/rs6000/rs6000.c (rs6000_debug_reg_global): If
-mdebug=reg, print value of VECTOR_ELEMENT_SCALAR_64BIT.
* config/rs6000/vsx.md (vsx_extract_<mode>, V2DI/V2DF modes):
Optimize vec_extract of 64-bit values, where the value being
extracted is in the top word, where we can use scalar
instructions. Add direct move and store support. Combine the big
endian/little endian vector select load support into a single
insn.
(vsx_extract_<mode>_internal1): Likewise.
(vsx_extract_<mode>_internal2): Likewise.
(vsx_extract_<mode>_load): Likewise.
(vsx_extract_<mode>_store): Likewise.
(vsx_extract_<mode>_zero): Delete, big and little endian insns are
combined into vsx_extract_<mode>_load.
(vsx_extract_<mode>_one_le): Likewise.
* config/rs6000/rs6000.h (VECTOR_ELEMENT_SCALAR_64BIT): Macro to
define the top 64-bit vector element.
* doc/md.texi (PowerPC and IBM RS6000 constraints): Document wD
constraint.

* config/rs6000/altivec.h (vec_xxsldwi): Add missing define to
enable use of xxsldwi and xxpermdi builtin functions.
(vec_xxpermdi): Likewise.
* doc/extend.texi (PowerPC AltiVec/VSX Built-in Functions):
Document use of vec_xxsldwi and vec_xxpermdi builtins.
