aarch64: X-Gene: Adapt tuning struct for GCC 7.
* use generic_[addrcost/regmove]_cost
* use generic_approx_mode
* decrease memmove_cost to 4 (was 6)
* decrease issues_rate to 2 (was 4)
This should actually be 4 and we should use TARGET_SCHED_VARIABLE_ISSUE()
* relax function alignment to 8 (was 16)
* relax loop alignment to 4 (was 16)
* set max_case_values (switch-case) to 17 (was 0)
