279ba58edb Fixed bug #76275 
* Adjust IS_SERIALIZED() check to account for potential empty
  allocations at the end of the memory region.
* Deallocate empty allocation if all try/catch elements have been
  removed in the block pass (similar to what we do if all live
  ranges have been eliminated).

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.

372bf8a923 Fixed bug #75969 
Move NOP stripping out of zend_optimize_block: NOP stripping may
move instructions, which may invalidate a Tsource shared across
an extended basic block.

Instead of make update_op1_by_const supports FETCH_LIST(CASE), I think
disable it is more safe for 7.1
