490a49d0bb Use COPY_DEREF for DIM_IS and LIST_R as well 
Also add an upgrading note for the behavior change, not that we
expect anyone to be affected...

Use COPY_DEREF instead of COPY_UNREF 
This fixes the behavior when the storage location of the fetch is
modified before the operand is dereferenced by the using VM opcode.

Furthermore it elimiates references as a possible return value from
*_R opcodes, which will give us more opportunities for inferences,
in particular in regard to typed properties.

7498f0163b Fix handling of assign-ops on overloaded props with ref return 
Assign-ops and incdec on overloaded properties are implemented
using a read_property followed by write_property. Previously, if
__get() returned by-reference, pre-incdec and assign-op
additionally also modified the reference, while post-incdec worked
correctly.

This change synchronizes the three code-paths to not modify the
reference. The pre-incdec implementation matches the post-incdec
implementation, the assign-op implementation uses a distinct
result operand.

b0af9ac733 Avoid live range references in opcodes 
Don't store the live range of the freed variable for FREE_ON_RETURN
frees, instead look it up at runtime. As this is an extremely
unlikely codepath (in particular, it requires a loop variable with
a throwing destructor), saving the runtime lookup of the live range
is not worth the extra complexity this adds everywhere else.

7141631cc8 Change FETCH/ISSET instruction modifiers: 
- Get rid of ZEND_ISEMPTY and ZEND_ISSET_ISEMPTY_MASK. Use just single ZEND_ISSET bit to make distinct between isset() and empty()
- Use ZEND_FETCH_GLOBAL, ZEND_FETCH_LOCAL and ZEND_FETCH_GLOBAL_LOCK as bitmask
- Removed unused ZEND_FETCH_STANDARD
- Extended ZEND_FETCH_ARG_MASK
