are used as spills in insns during which it is live, and retry global
register allocation. Update all life information in the

(hard_reg_use_compare): Take bad_spill_regs into account.
(pseudos_counted): New static variable.

Initialize bad_spill_regs from bad_spill_regs_global, then merge any
hard registers explicitly used across the current insn into the set.
