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).

d7f2dc4ec6 Improve HashTable iterators handling: 
- Avoid iterators check/update on each HashTable update opration
- Keep position equal (or above) nNumUsed instead of HT_INVALID_IDX
- Fixed iterators handling in array_unshift()

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.

ef20d2990f Remove unnecessary CE_STATIC_MEMBERS() checks 
CE_STATIC_MEMBERS(ce) is destroyed after EG(active)=0 is set, so we
should never run into a situation where it is NULL inside the VM.

3a794d39f0 Avoid repeatable ARG_SHOULD_BE_SENT_BY_REF() checks in FETCH_*FUNC_ARG and following SEND_VAR_EX. Perform the check once in a new CHECK_FUNC_ARG opcode and reuse in the following FETCH_*FUNC_ARG and SEND_FUNC_ARG (SEND_VAR_EX replacement). 2018-02-05 19:40:06 +03:00

e0171ed9d0 Avoid another unused opline warning 
The unconditional opline load here used to be necessary for freeing
the return value in case of exception. However, this is no longer
the case, so using LOAD_OPLINE() should be sufficient now.
