Array shape is forgotten by adding some conditionals.

Bug report

It seems phpstan is "forgetting" the shape of an array by just adding 2 conditional statements.

Code snippet that reproduces the problem

https://phpstan.org/r/3412d834-a20f-4968-aeae-06b6b07e4463

Expected output

Array shape is not forgotten.

Did PHPStan help you today? Did it make you happy in any way?

1.8.5 caught some more issues to fix in our product!

Too me it's a duplicate of #7963 and #8004

Since the array_shape is very complex, it is simplified by phpstan.

@bendavies After the latest push in 1.8.x, PHPStan now reports different result with your code snippet:

@@ @@
  5: Dumped type: int
-10: Dumped type: int|string|null
+10: Dumped type: int

Full report

Line	Error
5	Dumped type: int
10	Dumped type: int

Seems like it's solved by phpstan/phpstan-src@43d3652...bd57fc5

Do you want to add a regression test @ondrejmirtes @rvanvelzen ? (I can do it if the test if wanted)
