Hi Pavel,

the commit b39e3f34c9de7ead6a11a74aa2de78baf41d81a7
("icount: fixed saving/restoring of icount warp timers") has changed
something that made timers test for target/xtensa unstable.
Specifically ccount_write case in the tests/tcg/xtensa/test_timer.S
now fails for me about half of the times it is run. Given that it is run
under -icount I guess this is a bug. Could you please take a look?

The minimal test case is available here:
  http://jcmvbkbc.spb.ru/~dumb/tmp/201803131306/test_timer.tst
It is run as
  qemu-system-xtensa -M sim -cpu dc232b -nographic -semihosting
-icount 7  -kernel ./test_timer.tst

Thanks.
