	* amd64-linux-tdep.h (enum amd64_syscall): New enum consts,
	to replace literal consts used in amd64-linux-tdep.c
	* linux-record.h (enum gdb_syscall): New enum consts, to replace
	literal consts used in amd64-linux-tdep.c and linux-record.c.
	* amd64-linux-tdep.c (amd64_canonicalize_syscall): New function,
	translate from native amd64 Linux syscall id to internal gdb id.
	(amd64_linux_syscall_record): Switch statement abstracted out
	and replaced with a call to amd64_canonicalize_syscall.
	* linux-record.c (record_linux_system_call): Replace literal
	consts with enum consts.
	* i386-linux-tdep.c (i386_canonicalize_syscall): New function,
	trivially translate from native i386 Linux syscalls to gdb syscalls.
	(i386_linux_intx80_sysenter_record):
