Hi guys,
I make a new version to fix the error. Please help me review it.
Thanks,

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.
