Same as with property types, we no longer require that all constants
are resolved for preloading to work, it's just an optimization. As
such, drop the forced resolution for include-based preloading and
just keep the optimization.
Having all property types resolved is no longer a hard requirement
for preloading, resolving the types is just an optimization. As
such, drop the special logic that forced loading of property
types when include-based preloading is used. Instead only keep
the code that resolves types based on actually preloaded classes.
Also drop the ZEND_ACC_PROPERTY_TYPES_RESOLVED flag, which is now
nearly useless and takes up flag space...
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.
During preloading, check that all classes that have been included
as part of the preload script itself (rather than through opcache_compile_file)
can actually be preloaded, i.e. satisfy Windows restrictions, have
resolved initializers and resolved property types. When resolving
initializers and property types, also autoload additional classes.
Because of this, the resolution runs in a loop.
