The tempnam documentation currently states that "Only the first 63
characters of the prefix are used, the rest are ignored". However when
the prefix is 64 characters-long, the current implementation fails to
strip the last character, diverging from the documented behavior. This
patch fixes the implementation so it matches the documented behavior for
that specific case where the prefix is 64 characters long.

This method had some useless logic in it. It checked whether the child
node is a child of its parent, which is always true of course.
But I know where this check comes from, if you follow the spec closely
you'll find that the spec used to have explicit child and parent
arguments for the removal algorithm [1].
That's because that algorithm is written in a generic way, where the
parent and child arguments might not come from the same subtree.
However, in this particular case it *is* always the case that the child
is a child of its parent. The checks weren't needed back then for
DOMChildNode::remove(), and are still not needed today.

It should be incredibly rare for something to fail only without opcache while
also being platform specific. We're keeping opcache-less tests for x64 Linux,
macOS and i386 will continue to be tested without opcache in nightly.

Mostly, extensions will use `PHP_VERSION` and `PHP_VERSION_ID`
respectfully but sometimes they want to grab the version at run-time
rather than at compile-time. For example, extensions which distribute
pre-built binaries may want this.
Commit 0b2e6bc2b0 started caching the directory entry type to improve
performance. Shortly after, we've seen flaky failures of the
buildFromIterator phar test.
When it fails, it's always a value error in the constructor of
RecursiveDirectoryIterator::__construct() with a "no such file or
directory" error. What's happening here is this:
1) A parallel test creates a subdirectory in the current working dir.
2) This test checks hasChildren() on a directory entry, the cached entry
returns "yes" on the subdirectory.
3) The parallel test finishes and removes the subdirectory.
4) The constructor mentioned above is called, causing an exception
because the directory is gone.
This race has always been possible, even before said commit. It's just
that it was very hard to hit before: the expensive stat call made the
race window hard to hit. The race is now easier to hit because of the
caching that is fast.
Since there's many tests that modify the current working directory, it
seems best to mark this as an "all" conflict. We cannot avoid every
TOC-TOU race when working with files with these phar tests.
In particular, mounteddir.phpt caused every conflict I saw on CI, but
there's more tests that create subdirectories in the current working
directory.

People relied on manually waiting for children, but the fix for GH-11498
broke this. Fixing this in PHP is fundamentally incompatible with doing
the wait loop in userland. This reverts to the old behaviour.
Closes GH-11863.
