Make throw statement an expression

RFC: https://wiki.php.net/rfc/throw_expression

This has an open issue with temporaries that are live at the time
of the throw being leaked. Landing this now for easier testing and
will revert if we cannot resolve the issue.

Closes GH-5279.

Revert "Fetch for read in nested property assignments"

This reverts commit bb43a3822e42dbd15b1d416a166549d3980b379a.

After thinking about this a bit more, this is now going to be
a complete solution for the "readonly properties" case, for example:

unset($foo->readOnly->bar);

should also be legal and

$foo->readOnly['bar'] = 42;

should also be legal if $foo->readOnly is not an array but an
ArrayAccess object.

I think it may be better to distinguish better on the BP_VAR flag
level. Reverting for now.

Fetch for read in nested property assignments

$a->b->c = 'd';

is now compiled the same way as

$b = $a->b;
$b->c = 'd';

That is, we perform a read fetch on $a->b, rather than a write
fetch.

This is possible, because PHP 8 removed auto-vivification support
for objects, so $a->b->c = 'd' may no longer modify $a->b proper
(i.e. not counting interior mutability of the object).

Closes GH-5250.

Require non-absolute trait method refs to be unambiguous

Currently, when writing something like

class X {
use T1, T2 {
func as otherFunc;
}
function func() {}
}

where both T1::func() and T2::func() exist, we will simply assume
that func refers to T1::func(). This is surprising, and it doesn't
really make sense that this particular method gets picked.

This commit validates that non-absolute method references are
unambiguous, i.e. refer to exactly one method. If there is
ambiguity, it is required to write T1::func as otherFunc or
similar.

Closes GH-5232.
