Quoting original issue (fixes#5761):
> Given this snippet ( https://psalm.dev/r/4d51eeab35 ):

> ```php
> <?php
>
> function invalidate_cache_for(string $path): void {
> opcache_invalidate($path);
> }
>
> invalidate_cache_for('foo');
> ```

> Psalm reports the `opcache_invalidate()` call as `UnusedFunctionCall`. I'm wondering if `opcache_invalidate()` is perhaps inferred as a pure function? The only reference to it that I could find is in 1a59e81808/dictionaries/CallMap.php, but no purity markers are there.

Handle array plus operator (fixes#5588).
Handle array spread operator.
Improve string concatenation to resolve to literal instead of unknown string.
I feel like it should be possible to let ConstantTypeResolver take advantage of
the better type analysis in ArrayAnalyzer, ConcatAnalyzer, etc, but it would
require a restructuring that's beyond me for the time being.
* Sort uses
* Add ErrorHandler
* Use new error handler
* Drop old exception handler
* Suppress error-triggered exceptions during external autoload calls
* Add completions for functions
Provide autocompletions in the LSP for all global functions and functions from namespaces used in the current context.
* Uncomment code
* PHPCS
* Simplify functions map

* Switch to storing lowercase function string in array key
* Fix spacing

* Support compleitions on class references
This provides completions on class references (as opposed to initiated objects via the type map), so you can do `MyClass::` and get completitions for static methods and constants etc.
* Only provide completions for references that don't exist
* Remove file map cache when re-analyzing files
When the project is re-analyzed under the single thread condition (not using a process pool), the filemaps are not cleared before re-analyzing files. This means that file maps only get appended to. If you delete the contents of a file via the LSP, the file map will still be populated with all the old values for example.
In doing this I had to write a few more tests to check my assumptions too, so adding those additional tests.
* Rename test
* Formatting
* Formatting again!
