We need to extend the hash table before performing raw append
operations.
This doesn't matter if preloading happens in the same process,
as the tables will be large enough to hold all entries as a
side-effect of the preloading process. However, if preloading
happens in a different process, we need to reserve space here.

Attempting to require a file with (unset) casts results in an E_COMPILE_ERROR
that can't be caught or handled by set_exception_handler/set_error_handler.
Also remove the (bool) cast, because the ZEND_BOOL opcode handles that.
Remove inference that array -> object cast can throw.
It was added in 2a286ad599 - I don't know how creating an stdClass would throw.
(numeric keys, references, etc. don't cause it to throw)
Closes GH-5042
Internal constants can be marked as CONST_DEPRECATED, in which
case accessing them will throw a deprecation warning.
For now this is only supported on global constants, not class
constants. Complain to me if you need to deprecate a class
constant...
Closes GH-5072.
The op2 of FE_FETCH is only written if the loop edge is taken.
Fix up the SSA form to use the pre-assignment value if the exit
edge is taken.
This allows us to properly infer the type of the loop variable,
without letting the pre-loop type leak in.
Closes GH-5040.
Instead of having a completely independent encoding for type list
entries. This is going to use more memory, but I'm not particularly
concerned about that, as type unions that contain multiple classes
should be uncommon. On the other hand, this allows us to treat
top-level types and types inside lists mostly the same.
A new ZEND_TYPE_FOREACH macros allows to transparently treat list
and non-list types the same way. I'm not using it everywhere it could be
used for now, just the places that seemed most obvious.
Of course, this will make any future type system changes much simpler,
as it will not be necessary to duplicate all logic two times.
Convert the empty string assignment to an Error as per RFC [1]
Add a warning that only the first byte will be assigned to the offset if provided
a needle that is longer than one byte.

Due to ASLR restrictions, preloading on Windows does not work with
any code that has preloading dependencies on internal classes.
This effectively makes it unusable for any non-trivial codebase.
Instead of pretending like preloading is going to work, only to
make people realize that it really doesn't once they get beyond
a dummy example, we disable support for preloading on Windows
entirely.
Closes GH-4999.
Fix file cache serialization of property types. I'm changing the
overall type serialization format to perform additional adjustments
in order to yield a plausible pointer for zend_type, rather than
using an entirely separate serialization format, as was previously
done. That would have been annoying to extend to the case of CE
pointers.
If the script was serialized as file_cache_only (thus non-immutable)
and then gets unserialized into SHM, we need to allocate a new
run_time_cache slot and can't use the serialized arena pointer.
We must not use the same shared memory OPcache instance for different
SAPIs, since their memory layout is different. To avoid this, we add
the SAPI name (truncated to at most 20 characters) to the names of the
memory base file, the mutex and the file mapping.
