S/390: Disable vectorization for loops with few iterations

The following patch defines the PARAM_MIN_VECT_LOOP_BOUND parameter in
the s390 backend.  It helps with the vectorization epilogue problem
described here [1].
I see an overall performance increase of > 1% in SPECfp2006, yet some
cases like cactusADM regress.  This seems to be caused by the vectorizer
creating an epilogue guard for one more iteration than before, which, in
turn, causes e.g. predcom to run on the epilogue that it used to ignore
before ("Loop iterates only 1 time, nothing to do.").  Subsequent,
minor, effects cause an eventual slowdown.

Until the reason for the bad epilogue code is understood, this patch
mitigates the problem.  When investigating the issue, I stumbled across
an attempt to vectorize the epilogue itself as well as combine it with
the vectorized loop in addition to vector masking [2].  A similar
approach might also help here.  My original observation of high register
pressure within the epilogue still stands.  In this specific case, it
would most likely suffice to save all registers once, run the epilogue
and restore the registers.  I'm pretty sure this would be faster than
the "spill fest" that's currently happening.

(vec_any_eq) Likewise.
* config/rs6000/rs6000-builtin.def (CMPNEF): Remove BU_P9V_AV_2
expansion for CMPNEF to remove support for xvcmpnesp instruction.
(CMPNED): Remove BU_P9V_AV2 expansion for CMPNED to remove
support for xvcmpnedp instruction.
(VCMPNEB_P): Replace BU_P9V_AV_P macro expansion with BU_P9V_AV_2
macro expansion so that Power9 implementation of vec_all_ne does
not use the AltiVec predicate framework.
(VCMPNEH_P): Likewise.
(VCMPNEW_P): Likewise.
(VCMPNED_P): Likewise.
(VCMPNEFP_P): Likewise.
(VCMPNEDP_P): Likewise.

framework.

BU_P9V_OVERLOAD_2 so that Power9 implementation of vec_all_ne does
not use the AltiVec predicate framework.
(VCMPAE_P): Add BU_P9V_OVERLOAD_2 macro to change implementation
of vec_any_eq to not use AltiVec predicate framework.
* config/rs6000/rs6000-c.c (rs6000_target_modify_macros): Add
support for predefined __POWER9_VECTOR__ macro to indicate that
Power9 instruction selection is enabled.
(altivec_overloaded_builtins): Remove extraneous
ALTIVEC_BUILTIN_VEC_CMPNE entry for overloaded
function argument types RS6000_BTI_bool_V16QI and
RS6000_BTI_bool_V16QI.  Remove erroneous ALTIVEC_BUILTIN_VEC_CMPNE
entry for overloaded function argument types RS6000_BTI_bool_V4SI
andRS6000_BTI_bool_V4SI, mapping to P9V_BUILTIN_CMPNEB.  Remove
two entries mapping to P9V_BUITIN_CMPNED and one entry mapping to
P9V_BUILTIN_CMPNEF to force use of instructions not specific to
Power9 for implementations of vec_cmpne.  Change the signature for
all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
(representing vec_all_ne) to remove the previously described first
argument of type RS6000_BTI_INTSI, as this was an artifact of
reliance on the AltiVec predicate framework, which is no longer
used in the implementation of these functions.  Add
P9V_BUILTIN_VEC_VCMPAE_P entries (representing the vec_anyeq
function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
since, unlike the AltiVec predicate framework implementation, we
do not share function descriptors between vec_alle and vec_anyeq.
(altivec_resolve_overloaded_builtin): Add SFmode and DFmode to the
set of modes that receive special treatment even when
TARGET_P9_VECTOR is true.  The special treatment emits code that
does not depend on Power9 instructions.
* config/rs6000/vector.md (vector_ne_<mode>_p): Change this
define_expand to not rely on AltiVec predicate framework.
(vector_ae_<mode>p): New define_expand to represent vec_any_eq
function.
(vector_ne_v2di_p): Change this define_expand to not rely on
AltiVec predicate framework.
(vector_ae_v2di_p): New define_expand to represent vec_any_eq
function.
(vector_ne_<mode>_p): Change this define_expand to not rely on
AltiVec predicate framework.
(vector_ae_<mode>p): New define_expand to represent vec_any_eq
function.
* config/rs6000/vsx.md (*vsx_ne_<mode>_p): For modes VSX_EXTRACT_I
(V16QI, V8HI, V4SI), correct a typo in the code emitted for this
define_insn pattern.
(*vsx_ne_<mode>_p): For modes VSX_F (V4SF and V2DF), remove this
define_insn pattern because the xvcmpne<VSs>. instruction is not
supported.
(vcmpne<VSs>): Remove this define_insn because xvcmpne<VSs>
instruction is not supported.
