6579e48417 Introduced BIND_STATIC opcode instead of FETCH_R/FETCH_W(static)+ASSIGN/ASSIGN_REF (similar to BIND_GLOBAL). 
In the future we may refer to static variable by index instead of name, to eliminate hash lookup.

baf97b1fcc We don't nees zend_op_array->brk_cont_array at run-time anymore. 
Move zend_op_array->brk_cont_array into CG(context).brk_cont_array.
Use more compact zend_op_array->live_range instead of zend_op_array->brk_cont_array.
Semantic is kept unchanged.

cc3c425af8 Fix bug #70662 
This replaces add_new with update for the RW case. This should not
be problematic for performance, as this branch throws a notice.

Alternatively add_new could also be replaced with add. I went with
update, because it makes $a[0] += 1 behavior the same as
$a[0] = $a[0] + 1.

66754585f8 Fixed bug #70321 (Magic getter breaks reference to array property) 
Note that the UNEXPECTED(zv) was turned into EXPECTED(zv), as zv is mostly set in the context where it is used and usually anyway is checked first with OP*_TYPE == IS_VAR; or maybe just completely remove that (UN)EXPECTED at this place...

301ee26568 Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). 
CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE().
As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.
