Extract assign_dim_array_result_type() helper that can be reused
for INIT_ARRAY and implements all this logic correctly.

Test case "ext/standard/tests/array/range.phpt" failed on ARM64 machine
only under RELEASE mode.
How to reproduce it:
```
./buildconf -f; ./configure; make -j 128
make test TESTS="-d opcache.enable=1 -d opcache.enable_cli=1 ext/standard/tests/array/range.phpt"
```
Root cause:
I suspect the root cause is that on ARM64 machine, PHP RELEASE mode
produces different values for internal function range() compared to
DEBUG mode.
Take the downsized test case downsize-range.php [1] as an example. We
applied the check-element.diff patch to check the original values. Note
that we print out the floating point numbers with precision 16.
From the outputs in file output.md, we can see the 7-th and 9-th
elements are different between RELEASE and DEBUG.
To be honest, I didn't get where such difference comes from and probably
this is due to different compilation options used by RELEASED and DEBUG.
Fix:
After commit [2], serialize_precision is used for var_dump(). As a
result, the pre-set "precision=14" didn't work actually.
In this patch, we turn to set serialize_precision as 14 and therefore
the difference between RELEASE and DEBUG can be eliminated.
Note-1: this failue didn't occur on x86 machine.
Note-2: in my local test, this is the only test case which behaves
differently on ARM64 machine under RELEASE and DEBUG mode.

Same as with other exceptions during inheritance, convert those
thrown during delayed class loading into fatal errors. We can't
properly deal with such exceptions, as inheritance cannot be
gracefully aborted at this point.
Fixes oss-fuzz #39405.
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".
This reverts commit ac34648cf6.
As pointed out on GH-6783, the new format doesn't match any of
the specified formats. Previously the constant generated
Thursday, 14-Jul-2005 22:30:41 BST
which is obsolete. Now it generates
Thu, 14-Jul-2005 22:30:41 BST
which is not specified at all. The correct version would be:
Thu, 14 Jul 2005 22:30:41 BST
Reverting the change for now.
We address the `::setSize(0)` case by setting `array->element = NULL`
and `array->size = 0` before we destroy the elements.
