Currently, most skip checks are just for making sure an extension is
available. Even with recent addition of skip caching, this makes tests
needlessly slow:
* Checks for the same extension in its tests can have small differences
impacting cacheability.
* Even identical skip checks in two tests can still be executed twice if
they're run by different workers.
To remedy this, I'm repurposing the existing --EXTENSIONS-- section of
.phpt files to specify wjich extensions are required for current test to
run. Current behavior:
1) If the extension is already visible to PHP, all is good
2) If it isn't, assume it's present as a shared module and attempt to add
it via a command line parameter
3) If that works, all is good
4) If it doesn't, PHP fails with a cryptic error message trying to
execute the test itself
After this commit:
1) and 2) are kept unchanged
3) Check if shared extension file from 2) is actually present
4) Skip the test if it isn't
Other benefits include clear skip reasons (vs. sometimes none in many
current skip checks) and moving test information from code to metadata,
opening more opportunities for search and analysis.
Since --EXTENSIONS-- is barely ever used, this change poses no risk of
hidden failures.
As a demonstration of the new approach, this commit migrates one
extension to it. If merged, I will migrate other extensions in
subsequent PRs.

There is no need to require a (valid) save_handler to be set, when a
user handler is supposed to be set. We just have to make sure, that
no user handler is already set in this case.
Closes GH-6788.
Even if we don't know the exact method being called, include it
in the call graph with the is_prototype flag. In particular, we
can still make use of return types from prototype methods, as
PHP 8 makes LSP violations a hard error.
Most other places are adjusted to skip calls with !is_prototype.
Maybe some of them would be fine, but ignoring them is conservative.
Even if an explicit return type is given, we might still infer
a more narrow one based on return statements. We shouldn't
pessimize this just because a type has been declared.
We have separate flags for non-autoloading class fetches and
silent class fetches. There's no reason why NO_AUTOLOAD should
be special-cased to be implicitly silent.
It is not guaranteed, that the driver inserts only a single NUL byte at
the end of the buffer. Apparently, there is no way to find out the
actual data length in the buffer after calling `SQLGetData()`, so we
adjust after the next `SQLGetData()` call.
We also prevent PDO::ODBC_ATTR_ASSUME_UTF8 from fetching garbage, by
fetching all chunks with the same C type.
Closes GH-6716.
The compile context is shared between patterns, so we need to set
the character tables unconditionally in case we switched from
a non-C locale to the C locale.
Now that constants can contain objects (currently only enums),
we should destroy them before we free the object store, otherwise
there will be false positive leak reports.
This doesn't affect the fast_shutdown sequence.
