* tree.h (BUILT_IN_CALLER_RETURN_ADDRESS): Unused. Kill.
(BUILT_IN_FP, BUILT_IN_SP, BUILT_IN_SET_RETURN_ADDR_REG): Kill.
(BUILT_IN_EH_STUB_OLD, BUILT_IN_EH_STUB, BUILT_IN_SET_EH_REGS): Kill.
(BUILT_IN_EH_RETURN, BUILT_IN_DWARF_CFA): New.
* c-decl.c (init_decl_processing): Update accordingly.
* expr.c (expand_builtin): Likewise.
* cp/decl.c (init_decl_processing): Likewise.
* rtl.h (global_rtl): Add cfa entry.
(virtual_cfa_rtx, VIRTUAL_CFA_REGNUM): New.
(LAST_VIRTUAL_REGISTER): Update.
* emit-rtl.c (global_rtl): Add cfa entry.
(init_emit): Initialize it.
* function.c (cfa_offset): New.
(instantiate_virtual_regs): Initialize it.

Provide a dummy definition for non-windowed targets.
(get_reg_addr): New function.
(get_reg, put_reg, copy_reg): Use it.
(__throw): Rely on in_reg_window, not INCOMING_REGNO. Kill stub
generating code and use __builtin_eh_return. Use __builtin_dwarf_cfa.
