Make more use of rtx_vector_builder
This patch makes various bits of CONST_VECTOR-building code use
rtx_vector_builder, operating directly on a specific encoding.
2018-01-02 Richard Sandiford <richard.sandiford@linaro.org>
gcc/
* expr.c: Include rtx-vector-builder.h.
(const_vector_mask_from_tree): Use rtx_vector_builder and operate
directly on the tree encoding.
(const_vector_from_tree): Likewise.
* optabs.c: Include rtx-vector-builder.h.
(expand_vec_perm_var): Use rtx_vector_builder and create a repeating
sequence of "u" values.
* vec-perm-indices.c: Include rtx-vector-builder.h.
(vec_perm_indices_to_rtx): Use rtx_vector_builder and operate
directly on the vec_perm_indices encoding.
