Add AMD64 process record instruction set support.

	* i386-tdep.h (gdbarch_tdep): Add record_regmap for registers
	because the AMD64's registers order in GDB is not same with
	I386 instructions.
	Add i386_syscall_record to be the syscall function handle
	interface.
	(record_i386_regnum): Number for record_regmap.
	* i386-tdep.c (OT_QUAD): For 64 bits.
	(i386_record_s): Add rex_x, rex_b, rip_offset and
	popl_esp_hack for AMD64 instruction set. And regmap for
	record_regmap.
	(i386_record_lea_modrm_addr): Support AMD64 instruction set
	64 bits lea.
	(i386_record_lea_modrm): Ditto.
	(i386_record_push): New function.  Record the execution log
	of push.
	(I386_RECORD_ARCH_LIST_ADD_REG): New macro to record the
	register.
	(i386_process_record): Support AMD64 instruction set.
	* amd64-tdep.c (amd64_record_regmap): For record_regmap.
	(amd64_init_abi): Set amd64_record_regmap to record_regmap.
