Removed commented code

CONCAT optimization

Avoid useless duplication. Constant values have to be duplicated only for internal constants in ZTS build, to prevent simultaneous modification of reference counters from different threads.

Reorder conditions to check for fast paths first.

Fixed bug #69732 (can induce segmentation fault with basic php code).

Add test for memory leak with wrong return type

Fix memory leak with return types upon failure
TMP/VAR wasn't being freed in VERIFY_RETURN

Fixed typo

Fixed bug #69700 (tests/lang/this_assignment.phpt memory errors)

Remove ZEND_BRK/ZEND_CONT from VM

These are no longer used at run-time now, only temporarily during
compilation.

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 dynamica

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.

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.

Micro optimization

Fixed bug #69649 (segfault with --enable-dtrace)

Don't write prop if read prop threw exception

Fixed memory leak

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

Fix bug #69599

Mark first call frames of stack segment with ZEND_CALL_ALLOCATED flag to simplify checks on stack deallocation.

Add support for $callable() sytnax with 'Class::method'

Add support for $callable() sytnax with 'Class::method'

Using the $callable() syntax when used with a string of
the form 'Class::method' would error as an undefined
function, even if the string passed is_callable() or the
callable type-hint. The fix adds support for the $callable()
syntax for any string accepted by is_callable() or the
callable type-hint.

Fix bug 68475 test with deprecated notice

Reduced scope of unit test.

Added tests with arguments.

Fix static closure error in call_user_func opcode

I'm assuming this is the only error that is_callable() can generate
with retval=1.

This problem manifested after making closure

Fix static closure error in call_user_func opcode

I'm assuming this is the only error that is_callable() can generate
with retval=1.

This problem manifested after making closures in static methods
not implicitly static, but would also occur when binding any non-static
closure to a scope without a $this.

Improved fast path locality

Avoid unnecessary reference counter incrementation on $this when call methods

Fix LSB handling for closures

Closures will now use the called_scope from their instantiation
site. If they are rebound either the class of $this is used or if
no $this is provided the bound scope is used.

With this change the scope for static closures can be changed back
to use EG(scope) rather than EX(called_scope), thus fixing
bug #69568.

Throw exception from FETCH_CLASS_NAME

Instead of empty strings.

This does not affect the existing case of __CLASS__ in traits as
a scope will always exists in that case.
