Add missing zend_do_free call

This is a followup to d53f1bf8ab. When the yield *statement* is used its
return value still needs to be freed.

Remove implementation stubs for yield delegation

I decided to leave out yield delegation for an initial proposal, so remove
the stubs for it too.

Remove reference restrictions from foreach

foreach only allowed variables to be traversed by reference. This never
really made sense because

a) Expressions like array(&$a, &$b) can be meaningfully iterated by-ref
b) Function calls can return by-ref (so they can also be meaningfully
iterated)
c) Iterators could at least in theory also be iterated by-ref (not
sure if any iterator makes use of this)

With by-ref generators the restriction makes even less sense, so I removed
it altogether.

Require parenthesis around yield expressions

If yield is used in an expression context parenthesis are now required.
This ensures that the code is unambiguos.

Require parenthesis around yield expressions

If yield is used in an expression context parenthesis are now required.
This ensures that the code is unambiguos.

Yield statements can still be used without parenthesis (which should be
the most common case).

Also yield expressions without value can be used without parenthesis,
too (this should be the most common case for coroutines).

If the yield expression is used in a context where parenthesis are required
anyway, no additional parenthesis have to be inserted.

Examples:

// Statements don't need parenthesis
yield $foo;
yield $foo => $bar;

// Yield without value doesn't need parenthesis either
$data = yield;

// Parentheses don't have to be duplicated
foo(yield $bar);
if (yield $bar) { ... }

// But we have to use parentheses here
$foo = (yield $bar);

This commit also fixes an issue with by-ref passing of $foo[0] like
variables. They previously weren't properly fetched for write.

Additionally this fixes valgrind warnings which were caused by access to
uninitialized memory in zend_is_function_or_method_call().

Remove asterix modifier (*) for generators

Generators are now automatically detected by the presence of a `yield`
expression in their body.

This removes the ZEND_SUSPEND_AND_RET

Remove asterix modifier (*) for generators

Generators are now automatically detected by the presence of a `yield`
expression in their body.

This removes the ZEND_SUSPEND_AND_RETURN_GENERATOR opcode. Instead
additional checks for ZEND_ACC_GENERATOR are added to the fcall_common
helper and zend_call_function.

This also adds a new function zend_generator_create_zval, which handles
the actual creation of the generator zval from an op array.

I feel like I should deglobalize the zend_create_execute_data_from_op_array
code a bit. It currently changes EG(current_execute_data) and
EG(opline_ptr) which is somewhat confusing (given the name).

Fixed bug #62357 (compile failure: (S) Arguments missing for built-in function __memcmp).

Any C library function may be a macro, We should avoid using ZEND_STRS(L) as their arguments

Add sceleton for yield* expression

This does not yet actually implement any delegation.

Add support for yielding keys

Keys are yielded using the

yield $key => $value

syntax. Currently this is implemented as a statement only and not as an
expression, because conflicts arise considering nesting and use in arrays:

yield yield $a => $b;
// could be either
yield (yield $a) => $b;
// or
yield (yield $a => $b);

Once I find some way to resolve these conflicts this should be available
as an expression too.

Also the key yielding code is rather copy-and-past-y for the value yielding
code, so that should be factored out.

Allow to use yield without value

If the generator is used as a coroutine it often doesn't make sense to yield
anything. In this case one can simply receive values using

$value = yield;

The yield here will simply yield NULL.
