Handle promoted exception in int|string type

Fixes oss-fuzz #35790.

Fix return value of wrong fucntion by-ref assign

We should be using the result of zend_assign_to_variable() here,
which will deref prior to potential freeing.

Fixed bug #81090

For concatenation, the in-place variant can be much more efficient,
because it will reallocate the string in-place. Special-case the
typed property compound assignment code for the case where we
concatenate to a string, in which case we know that the result
will also be a string, and we don't need the type check anyway.

Implement never return type

The never type can be used to indicate that a function never
returns, for example because it always unwinds.

Accept zend_string instead of zval in compile_filename

Fast Class Cache

This is generalization of idea, that was previously usesd for caching
resolution of class_entries in zend_type. Now very similar mechanizm is
used for general zend_string into zend_class_entry resolution.

Interned zend_string with IS_STR_CLASS_NAME_MAP_PTR GC_FLAG uses its
refcount to adress corresponding zend_class_entry cache slot.
The refcount keeps an offset to this slot from CG(map_ptr_base).
Flag may be checked by ZSTR_HAS_CE_CACHE(str), cache slot may be read by
ZSTR_GET_CE_CACHE(str) and set by ZSTR_SET_CE_CACHE(str, ce).

Introduce pseudo-keyword ZEND_FALLTHROUGH

Set expectations

Changed PowerPC CPU registers used by Zend VM to work around GCC bug.

Old registers (r28/r29) might be clobbered by _restgpr routine used for return from C function compiled with -Os.

Drop unneessary if branch and adjust arg_num type

This if branch seems to be a remain of when certain type errors where E_WARNINGs, something which isn't the case since PHP 8.0.

Add zend_hash_lookup() and zend_hash_index_lookup() functions.
Thet search for an element with given key/index and add an empty one (NULL), if no found.

Change Zend Stream API to use zend_string* instead of char*.

This allows to eliminate re-calculation of string lenght and hash value.
