513b76794b Make zpp failures always throw, independent of strict_types 
Previously zend_parse_parameters (and FastZPP) would handle invalid
arguments depending on strict_types: With strict_types=1, a TypeError
is thrown, with strict_types=0 a warning is thrown and (usually) NULL
is returned. Additionally, some functions (constructors always and
other methods sometimes) opt-it to throwing regardless of strict_types.

This commit changes zpp to always generate a TypeError exception in
PHP 8.

a50198d0fe Implement ??= operator 
RFC: https://wiki.php.net/rfc/null_coalesce_equal_operator

$a ??= $b is $a ?? ($a = $b), with the difference that $a is only
evaluated once, to the degree that this is possible. In particular
in $a[foo()] ?? $b function foo() is only ever called once.
However, the variable access themselves will be reevaluated.

Don't automatically convert literal string keys to integers on
array access, as we may be dealing with an ArrayAccess object,
rather than a plain array.

Use COPY_DEREF instead of COPY_UNREF 
This fixes the behavior when the storage location of the fetch is
modified before the operand is dereferenced by the using VM opcode.

Furthermore it elimiates references as a possible return value from
*_R opcodes, which will give us more opportunities for inferences,
in particular in regard to typed properties.

95a0709935 Fix handling of ERROR zval in op1 of ASSIGN_REF 
If op1 is ERROR the behavior is to not perform any assignment and
return NULL. However, if the RHS was a by-value returning function,
we'd instead emit a notice and return the RHS as the return value
(even though the value was not assigned to anything -- the temporary
is immediately destroyed).

This normalized the behavior to always check for an ERROR in op1
first.

d877d18676 Error on by-ref assign to overloaded prop returning ref 
This error was already thrown if __get() was used -- however not
if it returned by reference. This is incorrect, because the
reference return makes no difference to a by-reference assignment,
which has reference-breaking semantics. The result was that the
assignment was accepted silently, even though it didn't do anything
(not even the value was assigned, let alone the reference).
