Marina Yatsina 13c308caeb Take into account the cost of local intervals when selecting split candidate. ... When selecting a split candidate for region splitting, the register allocator tries to predict which candidate will have the cheapest spill cost. Global splitting may cause the creation of local intervals, and they might spill. This patch makes RA take into account the spill cost of local split intervals in use blocks (we already take into account the spill cost in through blocks). A flag ("-condsider-local-interval-cost") controls weather we do this advanced cost calculation (it's on by default for X86 target, off for the rest).
