* Makefile.in (target-globals.o): Depend on $(CFGLOOP_H).
* cfgloop.h (target_cfgloop): New structure.
(default_target_cfgloop): Declare.
(this_target_cfgloop): Declare as a variable or define as a macro.
(target_avail_regs, target_clobbered_regs, target_res_regs)
(target_reg_cost, target_spill_cost): Redefine as macros.
* cfgloopanal.c (default_target_cfgloop): New variable.
(this_target_cfgloop): New conditional variable.
(target_avail_regs, target_clobbered_regs, target_res_regs)
(target_reg_cost, target_spill_cost): Delete.
* target-globals.h (this_target_cfgloop): Declare.
(target_globals): Add a cfgloop field.
(restore_target_globals): Copy the cfgloop field to
this_target_cfgloop.
