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.

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

91507ba6e8 Reduced VM code size. 
Made FETCH_DIM/OBJ_FUNC_ARG to dispatch ro corresponding FETCH_DIM/OBJ_R/_W handlers.
Merged TMP and VAR specializations of ZEND_FETCH_OBJ_R.
Allowed dispatching to less specialized handelrs and helpers. (e.g. from OP_TMP_CONST to OP_TMPVAR_CONST).

33b094479b TYPE_CHECK instruction changed. Now it keeps in extended_value a type mask. 
This makes check for "boolean" cheaper and allows check combination e.g. (is_string($a) || is_null($a))
