Directly operate on CONST_VECTOR encoding
This patch makes some pieces of code operate directly on the new
CONST_VECTOR encoding.
2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
gcc/
* cse.c (hash_rtx_cb): Hash only the encoded elements.
* cselib.c (cselib_hash_rtx): Likewise.
* expmed.c (make_tree): Build VECTOR_CSTs directly from the
CONST_VECTOR encoding.
