* tree-vect-loop.c (vect_compute_single_scalar_iteration_cost):
Pass
stmt_info to record_stmt_cost.
(vect_get_known_peeling_cost): Pass stmt_info if known to
record_stmt_cost.
* config/aarch64/aarch64-protos.h (cpu_vector_cost): Split
cpu_vector_cost field into
scalar_int_stmt_cost and scalar_fp_stmt_cost. Split vec_stmt_cost
field into vec_int_stmt_cost and vec_fp_stmt_cost.
* config/aarch64/aarch64.c (generic_vector_cost): Update for the
splitting of scalar_stmt_cost and vec_stmt_cost.
(thunderx_vector_cost): Likewise.
(cortexa57_vector_cost): LIkewise.
(exynosm1_vector_cost): Likewise.
(xgene1_vector_cost): Likewise.
(thunderx2t99_vector_cost): Improve after the splitting of the two
fields.
(aarch64_builtin_vectorization_cost): Update for the splitting of
scalar_stmt_cost and vec_stmt_cost.
