[AArch64] Enable VECT_COMPARE_COSTS by default for SVE
This patch enables VECT_COMPARE_COSTS by default for SVE, both so
that we can compare SVE against Advanced SIMD and so that (with future
patches) we can compare multiple SVE vectorisation approaches against
each other. It also adds a target-specific --param to control this.
