1a63fa6ec9 Implemented Request #76178 (Class constants are slow: they should be inlined at runtime) 
Run-time cache is used to eliminate recalculation of constant expression in RECV_INIT opcode (only non reference countable values are cached).

fcc08ce19f Prevent reference-counting on persistent zvals (internal constants, default properties and constants of internal classes). 
New macro ZVAL_COPY_OR_DUP() is used perform duplication, if necessary.
This should eliminate related race-coditions in ZTS build and prevent reference-counting bugs after unclean shutdown.

Prohibit direct update of GC_REFCOUNT(), GC_SET_REFCOUNT(), GC_ADDREF() and GC_DELREF() shoukf be instead.
Added mactros to validate reference-counting (disabled for now).
These macros are going to be used to eliminate race-condintions during reference-counting on data shared between threads.

5faedf5b3e 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.

9b61479166 We don't need to dup zend_class_constant here. 
quote why the internal class is still using duplication:
```
for internal classes, the zend_class_constant is malloc-ed. we need to
free it.

if (const->ce == ce) {
zval_ptr_dtor(&const->value);
free(const)
}
so, if two classes share one const, and it(parent class) was freed
before, this read(in child class, const->ce) is invalid..

and destroy_zend_class is called via zend_hash_destroy(class_table).
which is not in reverse order... so, parent classes are dtor first.

if we want this work, we should change that order.

88eae43ff9 Remove uses of VARs in extended_value 
The DECLARE_(ANON_)INHERITED_CLASS(_DELAYED) opcodes were
referencing the parent ce VAR through extended_value. This is
hacky and we can't track the def-use chain in SSA.

To avoid this, the layout of declaration opcodes is changed
as follows: op1 points to the lcname and rtd_key literals, in
that order. (For anon/lambda declarations only one of lcname or
rtd_key is present.) This frees up op2, which is now used to
reference the parent ce VAR in inheriting declarations. The
jmp offset for anon class declarations is moved frop op2 to
extended_value.

The changes were applied both to class and function declarations
to keep everything symmetric.

0919178963 Add result op for ASSERT_CHECK to fix SSA 
Otherwise one source of the phi node at the join point will be
borked.

I'm marking the ASSERT_CHECK result as unused in pass2, which is
a bit ugly.
