  Remove HOT attribute from some VM handlers. Comparisons almost always followed by JMPZ/JMPNZ; JMPZNZ is rare used.

b6f76aca54 Improve exception handling for abstract/deprecated calls 
Reuse existing arg freeing loop instead of duplicating it.

Additionally also handle deprecated in DO_FCALL_BY_NAME.

4bb7282742 Fix handling of abstract/deprecated exception 
The exception mechanism assumes that exceptions from DO_FCALL are
already happening after the function call. This means that we are
currently leaking the passed arguments, and I think we can also
corrupt the VM stack due to incorrect frame linking in some cases
(there are assertion failures if the VM stack page size is reduced).

Instead handle the stack frame freeing manually for this special
case.

603b9c43cb Add arg type assertions to DO_ICALL 
Now that DO_ICALL is also used for functions with type hints, we
should include the arginfo sanity check assertions in there as
well.

d93b094584 Throw TypeError from VM implementation of get_class() 
The normal function already throws TypeError through the usual zpp
mechanism, but the VM implementation handles this manually and has
not been updated.

afd96392a3 Revert "Use RW fetch for argument unpacking" 
This reverts commit 6913ec3282.
This reverts commit a9e332e027.

Causes https://bugs.php.net/bug.php?id=78356, which I don't have
a good solution for.

6913ec3282 Use RW fetch for argument unpacking 
Argument unpacking may need to create references inside the array
that is being unpacked. However, it currently can only do this
if a plain variable is unpacked, not for any nested accesses,
because the value is fetched for read. Resolve this by fetching
the operands for RW.

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.

9e4603f772 Try to fix macos build 
By avoiding unused variable opline warnings. Also clean up the
replacement of ZEND_VM_SPEC -- we were sometimes treating it as
an always-defined constant with a value (what it actually is) and
sometimes as a conditionally defined constant (which it isn't, but
which still worked thanks to the specializer). Switch to only
treating it as a constant with a value.
