Add REGISTERS_CLOBBERED_BY_SYSCALL for x86-64
X86-64 system calls use a different calling convention, which clobbers CC, %r11 an %rcx registers. Define REGISTERS_CLOBBERED_BY_SYSCALL for x86-64 inline asm statements. * sysdeps/unix/sysv/linux/x86_64/sysdep.h (REGISTERS_CLOBBERED_BY_SYSCALL): New. (INTERNAL_SYSCALL_NCS): Use it. (INTERNAL_SYSCALL_NCS_TYPES): Likewise.
