The hash is used to check whether the arginfo file needs to be
regenerated. PHP-Parser will only be downloaded if this is actually
necessary.
This ensures that release artifacts will never try to regenerate
stubs and thus fetch PHP-Parser, as long as you do not modify any
files.
Closes GH-5739.
These return an untyped protected property, so we can't rely on
the type being correct.
Also add return types to the interface -- normally this would be
a no-go, but Throwable is a special interface that can only
be implemented internally, so we control all implementations.
Closes GH-5353. From now on, PHP will have reflection information
about default values of parameters of internal functions.

We also change `Generator::throw()` to expect a `Throwable` in the
first place, and we now throw a TypeError instead of returning `false`
from `Exception::getTraceAsString()`.
