61a38bb274 SCCP: Fix leak when determining TYPE_CHECK from type info 
As TYPE_CHECK is the only opcode where we do something like this,
I'm adding this hack.

30f1b17262 Fix null check in sccp add_array_elem chain handling 
We need to check result_use rather than result_def for a null zval.
Previously we were later assuming that the null zval is really a
partial array, which does not go well.

bdce5849b7 Extract ct_eval_binary_op() 
And use it in more places, though some of them are currently not
reachable by partial arrays to the best of my knowledge.

Don't try to evaluate various operations with partial array operands.
We could evaluate some of these, but let's be conservative for now...

Properly check for array_replace_recursive in sccp.c 
Due to a typo, this code used to check for array_merge_recursive
twice.

ade702a0d2 Fixed bug #77434 
Mark arrays containing partial arrays as partial. This was already
done for the ADD_ARRAY_ELEMENT case, but not for ASSIGN_DIM.

4daa413898 Fixed bug #77092 
Weird that this worked for so long, probably because nearly all
ext/standard functions use fast ZPP rather than ordinary ZPP.

d9e71169e6 Fixed bug #75729 
Don't try to evaluate substr() and strpos() at compile-time if
mbstring function overloading is enabled. I'm reusing the
COMPILE_NO_BUILTIN_STRLEN for the detection of mbstring function
overloading here, even if it's technically only about strlen()...

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

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))
