IS_CONST operands don't have to be separated. Use reference-counting instead of duplication.

- with opcache all IS_CONST operands are not refcounted (scalars, interned strings or immutable arrays)
- without opcache IS_CONST operands are not shared between processes or threads and may use common reference counters

Merge zend_execute_data->called_scope into zend_execute_data->This.
"called_scope" made sense only for static method calls, for dynamic calls it was always equal to the class of $this.
Now EG(This) may store IS_OBJECT + $this or IS_UNUSED + "called_scope" (of course, "called_scope" may be NULL).
Some code might need to be adopted to support this change.
Checks (Z_OBJ(EX(This))) might need to be converted into (Z_TYPE(EX(This)) == IS_OBJECT).

Flags ZEND_CALL_RELEASE_THIS and ZEND_CALL_CLOSURE should never be set together.
Closures keep responsibility for releasing $this theirselves.

Use CALL_INFO flag to check if we need to destroy symbol_table.
This saves one memory load on most RETURN opcodes.

Sorry for that... Merged by accident....

Revert "Transparently introduce type-specialized opcode handlers."

This reverts commit 59d00b8bcc05f72b29c3c768542b2bb6e69e1af4.

Taking into account "undefined" variables

Transparently introduce type-specialized opcode handlers.
This affects only PHP VM, and doesn't change anything else.

More effecient fix for bug #71756

Add support for negative string offsets (syntax)

Fix "Call to member function on unknown"

Should be "on null".

Remove EXT_TYPE_UNUSED in favor of IS_UNUSED

This means we no longer allocate an unused VAR for the retval of
instructions that support unused results.

Nearly all instructions already used the result variable only if
it was used. The only exception to this was the return value
variable for internal function call results. I've adjusted the code
to use a stack zval for the unused return case now. As we have
retval specialization now, we know that it doesn't matter.
