zufuliu bff179888f Improve similar_text(), reduce recursive call to php_similar_char() 
If the longest common substring is the leftmost common substring, there
is no need to check the string prefixes for further common substrings,
since there are none.

Xinchen Hui c79f2de2cf Optimized strrev with SSSE3 
since strrev is not wildly used, and SSSE3 is defined default by some
compiler, so won't try to do ifunc here.

The ifunc attribute might be not available as it is binary format
dependent.

Xinchen Hui 98aa3a65c4 Optimized php_addslashes with SSE4.2 instructions 
According to benchmark
(https://gist.github.com/laruence/fd0d443d2c5bacca9d8ab99250499956) this brings 30%+ execution time reduced.

In the further, this open the door for possible SSE4.2 optimizations in
other places.

Tom Van Looy e4e26f2428 Remove RAND_RANGE() macro 
The behavior of RANGE_RANGE() is 7.1 changed completely, from
rescaling an already generated number to generating a number
itself. Because of this str_shuffle() ended up generating two
random numbers on every iteration.

To avoid further misuse the function is dropped entirely. Extensions
for PHP >= 7.1 should directly call php_mt_rand_range().

Anatol Belski c698299550 Interned strings unification for TS/NTS 
Hereby, interned strings are supported in thread safe PHP. The patch
implements two types of interned strings

- interning per process, strings are not freed till process end
- interning per request, strings are freed at request end

There is no runtime interning.

With Opcache, all the permanent iterned strings are copied into SHM on
startup, additional copying into SHM might happen on demand.
