And also cleanup anonymous class compiling, it make no sense prefix a
namespace to anonymous class name. and it is always lowcased and
interned string.

402f697068 Remove zend_init_list
No longer used - zend_add_to_list already covers this.

Also marked zend_add_to_list as static and dropped it from the header.

e13803d15b Inline zend_find_builtin_type

which is also used only one time.

339283c523 Rename some variables and functions
The way these are used have little to do with them being scalars;
they are just tuples with names, lengths and IS_* constants. We
will probably reuse these in the future with other types.

7a88d16cf3 Use ZEND_JMP instead of ZEND_BRK/ZEND_CONT
Emit necessary FREEs during compilation, convert to JMP during
pass_two (we may not know target opline beforehand).

9325ada725 Embed break/continue depth into opline
Previously a separate lval literal was used - this is probably a
leftover from the time where the break level could still be
specified dynamically.

3cbe3903fa Move loop var stack management into begin/end loop
Also set start to -1 in begin_loop already, so the info that a
loop variable is not used is already available at compile-time.

d0e265392f Drop FREE_ON_RETURN flag, check brk_cont->start instead
Start >= 0 already tells us whether or not the loop has a loop
variable, no need to add extra flags to opcodes.

Also added a test for a case where FREE_ON_RETURN is relevant,
we didn't seem to have any coverage for this.

6ef8ae65a2 Allow self etc in eval / file scope
This fixes a regression from 16a9bc1ec2.
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.

ab97606b8a Fix compiler assumptions about self/etc wrt closures
* Don't throw an error if self/parent/static are used in a closure
  (outside a class).
* Don't propagate self:: constants into closures
* Use runtime fetch for self::class in closures

Fixes bug #66811.

dd1fdfb17c 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.
