Add Linux AMD64 process record support.
* amd64-linux-tdep.c (amd64_linux_record_tdep): New variable.
This struct has the argument for the function
"record_linux_system_call".
(amd64_linux_syscall_record): New function. Parse the
system call instruction and call function
"record_linux_system_call" to record execute log.
(i386_linux_init_abi): Initialize "amd64_linux_record_tdep".
Set "amd64_linux_syscall_record" to "i386_syscall_record".
