* emit-rtl.c (static_regno_reg_rtx): Define.
(init_emit_once): Initialize static_regno_reg_rtx.
(init_emit): Copy static_regno_reg_rtx into regno_reg_rtx instead
of building new hard reg objects once per function.
(gen_rtx_REG): Try to share hard regs.
* regclass.c (init_fake_stack_mems): New function broken out from
init_regs.
* rtl.h (init_fake_stack_mems): Declare.
* toplev.c (lang_independent_init): Call init_regs before
init_emit_once. Call init_fake_stack_mems after init_emit_once.
