[4.8, 4.9] Backport of additional SLM tuning.
Six patches from trunk, reg-tested via 'make check':
2014-05-07 Evgeny Stupachenko <evstupac@gmail.com>
* tree-vect-data-refs.c (vect_grouped_load_supported): New
check for loads group of length 3.
(vect_permute_load_chain): New permutations for loads group of
length 3.
* tree-vect-stmts.c (vect_model_load_cost): Change cost
of vec_perm_shuffle for the new permutations.
2014-04-17 Evgeny Stupachenko <evstupac@gmail.com>
* config/i386/i386.c (x86_add_stmt_cost): Fix vector cost model for
Silvermont.
2014-04-17 Evgeny Stupachenko <evstupac@gmail.com>
* config/i386/x86-tune.def (TARGET_SLOW_PSHUFB): New tune definition.
* config/i386/i386.h (TARGET_SLOW_PSHUFB): New tune flag.
* config/i386/i386.c (expand_vec_perm_even_odd_1): Avoid byte shuffles
for TARGET_SLOW_PSHUFB
2014-04-17 Evgeny Stupachenko <evstupac@gmail.com>
* config/i386/i386.c (slm_cost): Adjust vec_to_scalar_cost.
* config/i386/i386.c (intel_cost): Ditto.
2014-06-18 Evgeny Stupachenko <evstupac@gmail.com>
* config/i386/i386.c (ix86_reassociation_width): Add alternative for
vector case.
* config/i386/i386.h (TARGET_VECTOR_PARALLEL_EXECUTION): New.
* config/i386/x86-tune.def (X86_TUNE_VECTOR_PARALLEL_EXECUTION): New.
* tree-vect-data-refs.c (vect_shift_permute_load_chain): New.
Introduces alternative way of loads group permutaions.
(vect_transform_grouped_load): Try alternative way of permutations.
2014-06-05 Evgeny Stupachenko <evstupac@gmail.com>
* config/i386/sse.md (*ssse3_palignr<mode>_perm): New.
* config/i386/predicates.md (palignr_operand): New.
Indicates if permutation is suitable for palignr instruction.
