Fix scope_is_known() for class constants

Here the active_op_array is still the surrounding file, but we
do know the scope.

Merged FE_FETCH_R[W] with the following ASSIGN[_REF] when assigne to CV.

Allow self etc in eval / file scope

This fixes a regression from 16a9bc1ec20533c76ba992bfc64dd69e7b7d9001.
Together with the recent closure related changes this should allow
all usages of self etc, while previously (in PHP 5) some things like
self::class did not work.

Use ZEND_FETCH_CLASS_NAME for dynamic self::class etc

Extend the opcode to support getting the parent and static name and
then use it for dynamic ::class resolution.

ext tokenizer port + cleanup unused lexer states

we basically added a mechanism to store the token stream during parsing
and exposed the entire parser stack on the tokenizer extension through
an opt in flag: token_get_all($src, TOKEN_PARSE).

this change allows easy future language enhancements regarding context
aware parsing & scanning without further maintance on the tokenizer
extension while solves known inconsistencies "parseless" tokenizer
extension has when it handles `__halt_compiler()` presence.

Also fix a bug with return types where "self" was rejected inside
a class, but not on a method.

Make it inline

Drop compile_class_decl return value

Was introduced for anon classes, but no longer needed.

Pass class_entry through IS_VAR to avoid hash lookup in ZEND_NEW.

Use "safe" anonymous class names. Don't show the mangled names through var_dump().

Refactored using specialized opcodes

Fix implementing_class handling

More cleanup (mainly retab)

Don't issue FETCH_CLASS for anon classes

More retab

Simply anon class name generation

Drop dead "parent" code

Retab

Revert unrelated changes / rebase fixup

Rebase Joe's anon classes implementation

Fix bug #69532

Partial revert of ea2fc7f935d2767c127756647f47be8d420346ce.

Dont't use DO_ICALL for internal functions returned by reference

Slight improvement
