5880428dac Fix potential memory issue with USE_ZEND_ALLOC=0 
The PHP core and extensions are written with the assumption that memory
allocation either succeeds, or the allocator bails out (i.e. the allocator
is infallible). Therefore the result of emalloc() and friends are not checked
for NULL values.

However, with USE_ZEND_ALLOC=0, malloc() and friends are used as allocators,
but these are fallible, i.e. they return NULL instead of bailing out if they
fail. This easily leads to invalid memory accesses in the following, such as
in <https://bugs.php.net/73032>. Some of these cases may constitute
exploitable vulnerabilities.

Therefore we make the infallible __zend_alloc() and friends the default for
USE_ZEND_ALLOC=0.

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.
