Add process record Linux system call 64 bits support.
* linux-record.h (linux_record_tdep): Add size_pointer,
size_size_t, size_iovec and arg6. Change the values of
size_int, size_long and size_ulong to
gdbarch_int_bit (gdbarch) / TARGET_CHAR_BIT,
gdbarch_long_bit (gdbarch) / TARGET_CHAR_BIT,
gdbarch_long_bit (gdbarch) / TARGET_CHAR_BIT.
* i386-linux-tdep.c (i386_linux_init_abi): Ditto.
(i386_linux_intx80_sysenter_record): Add a check for system
call number.
* linux-record.c (record_linux_system_call): Make this
function support 64 bits.
