Bug report

Trying to match against gettype does not work as expected.
This problem is maybe related also to this:
#4451

Code snippet that reproduces the problem

https://phpstan.org/r/db68feed-2dbb-43b8-bbb5-f7acbc65ef9e

Expected output

This code handle all possible results, following the function definition:

#[Pure]
#[ExpectedValues([
    "boolean", "integer", "double", "string", "array", "object", "resource", "NULL", "unknown type", "resource (closed)"
])]
function gettype(mixed $value): string {}

PHPStan also does not seems to understand that in line 11 the type of $value is narrowed and cannot be object or array
