Use AVX2 to accelerate strto{upper,lower} (only on 'AVX2-native' builds for now)

On short strings, there is no difference in performance. However, for
strings around 10,000 bytes long, the AVX2-accelerated function is
about 55% faster than the SSE2-accelerated one.

Tweak SSE2-accelerated strtoupper() and strtolower() for speed

Tweak SSE2-accelerated strtoupper() and strtolower() for speed

I learned this trick for doing a faster bounds check with both upper
and lower bounds by reading a disassembler listing of optimized code
produced by GCC; instead of doing 2 compares to check the upper and the
lower bound, add an immediate value to shift the range you are testing
for to the far low or high end of the range of possible values for the
type in question, and then a single compare will do. Intstead of
compare + compare + AND, you just do ADD + compare.

From microbenchmarking on my development PC, this makes strtoupper()
about 10% faster on long strings (~10,000 bytes).

Make strtolower() and strtoupper() do ASCII case conversion (#7506)

Implement RFC https://wiki.php.net/rfc/strtolower-ascii

Add upper case functions to zend_operators.c and use them (#7521)

Add a family of upper case conversion functions to zend_operators.c,
by analogy with the lower case functions.

Add upper case functions to zend_operators.c and use them (#7521)

Add a family of upper case conversion functions to zend_operators.c,
by analogy with the lower case functions.

Move the single-character conversion macros to the header so that they
can be used as a locale-independent replacement for tolower() and
toupper().

Factor out the ugly bits of the SSE2 case conversion so that the four
functions that use it are easy to read and processor-independent.

Use the new ASCII upper case functions in ext/xml, ext/pdo_dblib and as
an optimization for strtoupper() when the locale is "C".

Deprecate passing null to non-nullable arg of internal function

This deprecates passing null to non-nullable scale arguments of
internal functions, with the eventual goal of making the behavior
consistent with userland functions, where null is never accepted
for non-nullable arguments.

This change is expected to cause quite a lot of fallout. In most
cases, calling code should be adjusted to avoid passing null. In
some cases, PHP should be adjusted to make some function arguments
nullable. I have already fixed a number of functions before landing
this, but feel free to file a bug if you encounter a function that
doesn't accept null, but probably should. (The rule of thumb for
this to be applicable is that the function must have special behavior
for 0 or "", which is distinct from the natural behavior of the
parameter.)
