* config/rs6000/rs6000.c (rs6000_expand_builtin): Do not do the
switch statement mapping KF built-ins to TF built-ins if we don't
have the proper ISA 3.0 assembler support.

* config/rs6000/rs6000-c.c (is_float128_p): New helper function.
(rs6000_builtin_type_compatible): Treat _Float128 and long double
as being compatible if -mabi=ieeelongdouble.
* config/rs6000/rs6000-builtin.def (BU_FLOAT128_HW_1): New macros
to setup float128 built-ins with hardware support.

(BU_FLOAT128_HW_VSX_1): Likewise.
(BU_FLOAT128_HW_VSX_2): Likewise.
(scalar_extract_expq): Change float128 built-in functions to
accommodate having both KFmode and TFmode functions. Use the
KFmode variant as the default.

(scalar_test_neg_qp): Likewise.
(scalar_insert_exp_q): Likewise.
(scalar_insert_exp_qp): Likewise.
(scalar_test_data_class_qp): Likewise.
(sqrtf128_round_to_odd): Delete processing the round to odd
built-in functions as special built-in functions, and define them
as float128 built-ins. Use the KFmode variant as the default.

(fmaf128_round_to_odd): Likewise.
* config/rs6000/rs6000.c (rs6000_expand_binop_builtin): Add
support for KFmode and TFmode xststdcqp calls.
(rs6000_expand_builtin): If long double is IEEE 128-bit floating
point, switch the built-in handlers for the get/set float128
exponent, get float128 mantissa, float128 test built-ins, and the
float128 round to odd built-in functions. Eliminate creating the
float128 round to odd built-in functions as special built-ins.
(rs6000_init_builtins): Eliminate special creation of the float128
round to odd built-in functions.
* config/rs6000/vsx.md (xsxexpqp_<mode>): Change float128 built-in
function insns to support both TFmode and KFmode variants.
(xsxsigqp_<mode>): Likewise.
(xsiexpqpf_<mode>): Likewise.
(xsiexpqp_<mode>): Likewise.
(xststdcqp_<mode>): Likewise.
(xststdcnegqp_<mode>): Likewise.

* config/rs6000/rs6000-builtin.def (BU_FLOAT128_1): Delete
float128 helper macros, which are no longer used after deleting
the old 'q' built-in functions, and moving the round to odd
built-in functions to being special built-in functions.

built-in names to 'f128'.
* config/rs6000/rs6000.c (rs6000_fold_builtin): Remove folding the
old 'q' built-in functions, as the machine independent code for
'f128' built-in functions handles this.
(rs6000_expand_builtin): Add expansion for float128 round to odd
functions, keying off on -mabi=ieeelongdouble of whether to use
the KFmode or TFmode variant.
(rs6000_init_builtins): Initialize the _Float128 round to odd
built-in functions.
* doc/extend.texi (PowerPC Built-in Functions): Document the old
_Float128 'q' built-in functions are now mapped into the new
'f128' built-in functions.
