350082ed71 Fixed "opcache.file_cache_fallback" mode. 
It's not safe to change value of ZCG(accel_directives).file_cache_only, becuse it might be altered by INI subsystem.
Use global variable instead.

c0abab5fca Fix ZEND_SL range inference

move instructions, which may invalidate a Tsource shared across

7aac61ce76 Fixed bug #75938 
New modulus range inference implementation has been verified using
https://gist.github.com/nikic/67947ff92cf0e1f7e931f2f0d4cf817f.

The computed bounds are not tight, but it seems to be very hard to
compute tight bounds on modulus operations.

1391a0fa0b Fixed bug #75893 
It is not sufficient to just add the additional types for aliased
variables at the end of type inference, because types of derived
variables may depend on them. Make sure the additional types are
always added whenever the type of an aliased variable is updated.

d9e71169e6 Fixed bug #75729 
Don't try to evaluate substr() and strpos() at compile-time if
mbstring function overloading is enabled. I'm reusing the
COMPILE_NO_BUILTIN_STRLEN for the detection of mbstring function
overloading here, even if it's technically only about strlen()...
