14023d39c1 Move builtin_ctzl portability into zend_bitset.h 
Use this function in both zend_mm_bitset_find_one and
zend_bitset_first.

Maybe zend_bitset.h is not quite the right place for it, but I did
not want to include this in a globally included header like
zend_long.h or zend_portability.h.

b65b15c6f4 Mark assert() as INDIRECT_VAR_ACCESS 
I don't like this... we may want to detect "obviously not string"
operands by checking for the result of a comparison instruction.

8f7b1a3248 IS_CONST operands don't have to be separated. Use reference-counting instead of duplication. 
- with opcache all IS_CONST operands are not refcounted (scalars, interned strings or immutable arrays)
- without opcache IS_CONST operands are not shared between processes or threads and may use common reference counters

6079ba4b0c Inference: Fix undef handling for binary ops 
We need to be careful about correctly handling that undef results
in a null value. Otherwise, apart from simply generating incorrect
results, we may also end up performing non-monotonic lattice
transitions, thus causing an infinite type inference loop (see
test).

ccf18da450 Eliminated checks for (func->op_array.fn_flags & ZEND_ACC_GENERATOR) in fast path of DO_FCALL* handlers. 
This slightly improves calls to regular function and method calls in cost of a bit slower generator initialization.
Separate call frame for generators, allocated on heap, now created by ZEND_GENERATOR_CREATE instruction.

b1c3c9a525 Explicitly construct phi set during def propagation 
Previously the phi set was first computed during def propagation
and then computed again (per-block) during actual phi placement.
This commit changes this to store the phi set computed during
def propagation.

This makes SSA construction slightly faster (5%), but the main
purpose here is to pave the way for the next commit.

This also fixes a potential issue with the handling of irreducible
loops -- they generated additional phis, but these were not
accounted for in def propagation. (Though I'm not sure if we can
even have any irreducible loops right now.)

a73b03edea Fix serializing ZEND_AST_SHELL_EXEC 
Currently, `foo` is reserialized as `'foo'` due to misuse of zend_ast_export().
ZEND_AST_SHELL_EXEC can only contain ZEND_AST_ZVAL(string) or ZEND_AST_ENCAPS_LIST,
so just handle the ZEND_AST_ZVAL(string) case directly.

The problem is because we release p->value too early

and later you try to convert an object to string, which is a fatal error

then leave p->value double free, change to expect long is a BC break

Not sure what the previous fix was supposed to do. The issue was
that error_reporting() simply assumes that the value must either
be an integer or a string.

Fixed by using zpp properly.
