Makefile.in (final.o): Depend on target.h.

	* Makefile.in (final.o): Depend on target.h.
	* final.c: Include target.h.
	(default_function_pro_epilogue): New.
	(final_start_function): Use target structure for function prologues.
	(final_end_function): Use target structure for function epilogues.
	* fold-const.c (real_hex_to_f): Constify s and p.
	* output.h (default_function_pro_epilogue): New.
	* real.h (real_hex_to_f): Update prototype.
	* target-def.h (TARGET_ASM_FUNCTION_PROLOGUE,
	TARGET_ASM_FUNCTION_EPILOGUE, TARGET_ASM_OUT): New.
	(TARGET_INITIALIZER): Update.
	* target.h (gcc_target): Add struct asm_out.
	* doc/tm.texi: Update.

config:
	Update each arch to use TARGET_ASM_FUNCTION_PROLOGUE and
	TARGET_ASM_FUNCTION_EPILOGUE.  Move macro code to functions
	in cpu/cpu.c, or rename old functions consistently.  Take
	a HOST_WIDE INT not an int as the SIZE parameter.  Remove now
	redundant macros and prototypes.  Make new functions static.
