Implement Xtensa datapath_is_big_endian() helper via libisa.
Signed-off-by: Philippe Mathieu-Daudé <phi...@linaro.org>
---
Other accesses to xtensa_isa_internal fields don't
call cpu_synchronize_state(), and the libisa doesn't
provide a way to switch endianness from translation
code. Should we add a sync just in case?
