Avoid duplicate "non well-formed" warning

The arginfo checking code for internal functions should not generate
this warning, as it will be thrown by zpp.

Inline zend_zval_ptr() in executor explicitely (only on hot paths)

Mark _get_zval_ptr_deref as unused

Simplify TMP/VAR operand releasing

Try to fix macos build

By avoiding unused variable opline warnings. Also clean up the

Try to fix macos build

By avoiding unused variable opline warnings. Also clean up the
replacement of ZEND_VM_SPEC -- we were sometimes treating it as
an always-defined constant with a value (what it actually is) and
sometimes as a conditionally defined constant (which it isn't, but
which still worked thanks to the specializer). Switch to only
treating it as a constant with a value.

Deprecate array_key_exists() on objects

Separate "cold" and common unspecialized code

Remove unused _get_zval_ptr_cv_BP_VAR_UNSET function

To fix the macos -Werror build.

Delay IS_UNDEF checks

Separate "cold" parts of comparison instructions

Throw notice on array access on illegal type

No notice is thrown for list() accesses, because we did not come
to an agreement regarding patterns like

while ([$key, $value] =

Throw notice on array access on illegal type

No notice is thrown for list() accesses, because we did not come
to an agreement regarding patterns like

while ([$key, $value] = yield $it->next()) { ... }

where silent null access may be desirable.

No effort is made to suppress multiple notices in access chains
likes $x[0][0][0], because the technical complexity this causes
does not seem worthwhile.

Rename support_strings to !is_list

In preparation for more behavior that depends on whether it it is
a list() access. Using support_strings for that would be
confusing.

Replace ZEND_ASSIGN_ADD (and others) by ZEND_ASSIGN_OP, ZEND_ASSIGN_DIM_OP, ZEND_ASSGIN_OBJ_OP and ZEND_ASSIGN_STATIC_PROP_OP

Improve zend_binary_assign_op helpers.
Reorder opcode numbers to make ADD-POW and ASSIGN_ADD-ASSIGN_POW opcodes sequencional.

Better optimization in RELEASE build. ZEND_ASSERT(s) prevented optimization

Optimization of INC/DEC helpers

Fixed build without global register variables

Separate slow code

Micro-optimization

Remove unused zend_verify_arg_type() function

Cleanup

Change indexing scheme for symtable_cache

symtable_cache_ptr now points to the first unused symtable_cache
entry, rahter than the last used one. This avoids taking a pointer
to the m

Change indexing scheme for symtable_cache

symtable_cache_ptr now points to the first unused symtable_cache
entry, rahter than the last used one. This avoids taking a pointer
to the minus first element of the array, which is UB. Instead we
take a pointer to the end plus one, which is not UB.

Don't verify arginfo types for internal functions

To avoid duplicate type checks. In debug builds arginfo is still
checked and will generate an assertions if the function doesn't
subsequently throw an exception.

Some test results change due to differences in zpp and arginfo
error messages.
