2aba10be4a Reduce ZEND_THROW specialization 
Throwing is very expensive due to the need of gathering the backtrace,
so it makes little sense to optimize refcounting to this degree.

1eb706179f Avoid references in TMP var 
Make sure we deref the OBJ_IS result, because we store it in a TMP
var, which is not allowed to contain references and will cause
assertion failures in the unspecialized VM.

This also partially reverts fd463a9a60,
which merged the TMP and VAR specializations of COALESCE to work
around this bug.

An alternative would be to change the result type of OBJ_IS back
to VAR.

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.

f916d603ef - Add arginfo ZEND_ARG_SEND_AUTOMATIC which lets the compiler automatically 
determine whether pass by ref is possible or pass by value is needed.
# This is usefull when functions take array or string parameters as
# expressions. In such a case force by ref is not applicable and the
# executor would copy the variable unnecessarily as soon as it is at least
# once referenced.

db507dd153 - Commit the variable fetch optimization. 
- Extensions which delete global variables need to use new special function
- delete_global_variable() (I'm about to rename it) to remove them.
- Will post to internals@ or via commit messages if there's anything else.

8eb8850c90 - Some architectural changes: 
a) We specialize opcodes according to op_type fields. Each opcode has to
    be marked with which op_type's it uses.
 b) We support different execution methods. Function handlers, switch()
    and goto dispatching. goto seems to be the fastest but it really
    depends on the compiler and how well it optimizes. I suggest playing
    around with optimization flags.

- Warning: Things might break so keep us posted on how things are going.
