e13803d15b Inline zend_find_builtin_type 
This function was used only inside of zend_find_builtin_type_by_name,
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.

3dba00bc31 Fix scope_is_known() for class constants 
Here the active_op_array is still the surrounding file, but we
do know the scope.

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.

110759386e 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.

16a9bc1ec2 Disallow self etc outside classes at compile-time 
Also fix a bug with return types where "self" was rejected inside
a class, but not on a method.

Fallout: A couple of tests changed to more generic error messages.

d2607a0110 Move more stuff to file_context 
Introduce helper macro FC(x) for CG(file_context).x.

end_compilation() now handled by file_context_end().

While at it, dropped zval wrapper for ticcks.

0381c1b79e Fixed bug #69388 
Renamed compiler_context to oparray_context. Introduced per-file
file_context. Moved import tables into the file_context.

context_stack no longer exists, instead keeping backups of contexts
on C stack. Same for file contexts.

TODO: Move more things out of CG into file_context. There should be
a number of other things that we should not try to reuse in nested
compilations.
