i386: Add clear_ratio to processor_costs
i386.h has
#define CLEAR_RATIO(speed) ((speed) ? MIN (6, ix86_cost->move_ratio) : 2)
It is impossible to have CLEAR_RATIO > 6. This patch adds clear_ratio
to processor_costs, sets it to the minimum of 6 and move_ratio in all
cost models and defines CLEAR_RATIO with clear_ratio.
* config/i386/i386.h (processor_costs): Add clear_ratio.
(CLEAR_RATIO): Remove MIN and use ix86_cost->clear_ratio.
* config/i386/x86-tune-costs.h: Set clear_ratio to the minimum
of 6 and move_ratio in all cost models.
