Use (CONST_VECTOR|GET_MODE)_NUNITS in simplify-rtx.c
This patch avoids some calculations of the form:
GET_MODE_SIZE (vector_mode) / GET_MODE_SIZE (element_mode)
in simplify-rtx.c. If we're dealing with CONST_VECTORs, it's better
to use CONST_VECTOR_NUNITS, since that remains constant even after the
SVE patches. In other cases we can get the number from GET_MODE_NUNITS.

* simplify-rtx.c (simplify_const_unary_operation): Use GET_MODE_NUNITS
and CONST_VECTOR_NUNITS instead of computing the number of units from
the byte sizes of the vector and element.
(simplify_binary_operation_1): Likewise.
(simplify_const_binary_operation): Likewise.
(simplify_ternary_operation): Likewise.
