Fix symtable cache being used while cleaning symtable

We need to first clean the symtable and then check whether a cache
slot is available for it. Otherwise, it may happen that a destructor
runs while cleaning the table and uses up all the remaining slots
in the cache.

This is particularly insidious because once we overflow the cache,
the first pointer we modify is symtable_cache_ptr, making it hard
to understand what happened after the fact.

Deprecate passing null to non-nullable arg of internal function

This deprecates passing null to non-nullable scale arguments of
internal functions, with the eventual goal of making the behavior
consistent with userland functions, where null is never accepted
for non-nullable arguments.

This change is expected to cause quite a lot of fallout. In most
cases, calling code should be adjusted to avoid passing null. In
some cases, PHP should be adjusted to make some function arguments
nullable. I have already fixed a number of functions before landing
this, but feel free to file a bug if you encounter a function that
doesn't accept null, but probably should. (The rule of thumb for
this to be applicable is that the function must have special behavior
for 0 or "", which is distinct from the natural behavior of the
parameter.)

Added Inheritance Cache.

This is a new transparent technology that eliminates overhead of PHP class inheritance.

PHP classes are compiled and cached (by opcahce) separately, however their "linking" was done at run-time - on each request. The process of "linking" may involve a number of compatibility checks and borrowing methods/properties/constants form parent and traits. This takes significant time, but the result is the same on each request.

Inheritance Cache performs "linking" for unique set of all the depending classes (parent, interfaces, traits, property types, method types involved into compatibility checks) once and stores result in opcache shared memory. As a part of the this patch, I removed limitations for immutable classes (unresolved constants, typed properties and covariant type checks). So now all classes stored in opcache are "immutable". They may be lazily loaded into process memory, if necessary, but this usually occurs just once (on first linking).

The patch shows 8% improvement on Symphony "Hello World" app.

Add support for union types for internal functions

This closes the last hole in the supported types for internal
function arginfo types. It's now possible to represent unions of
multiple classes. This is done by storing them as TypeA|TypeB and
PHP will then convert this into an appropriate union type list.

Closes GH-6581.

The `zend_system_id` is a (true global) system ID that fingerprints a process state. When extensions add engine hooks during MINIT/startup, entropy is added the system ID for each hook. This allows extensions to identify that changes have been made to the engine since the last PHP process restart.
