JIT also works for non-ZTS PHP Windows builds now.


Thanks. Dmitry.

Owing to Dmitry's great work on this, the Windows part is now in a very goo=
d shape. Zend/bench.php shows at least 4x better performance with Opcache+J=
IT vs. just Opcache on current master. A dev snapshot x64/NTS of the today'=
s jit-dynasm branch are available here
