Remove name field from the zend_constant struct (#10954)

As global constant names are case-sensitive now, we don't have to store them separately above the constant table.

And drop Z_ACCESS_FLAGS(). We no longer store *only* access flags

run-time evaluation.

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 deprecating constants

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.
