[3.5 beta3] GDScript release builds can't infer type of builtin function return values

[ghost]

Godot version

3.5 beta3

System information

Linux, GLES 3, Intel Graphic UHD 630

Issue description

Game crashes when below gdscript is compiled in release mode (in debug mode it can run normally)

extends Node

const MIN_TIME = 800
var start_time: int

func _ready():
	start_time = OS.get_ticks_msec()

func _process(_delta):
	var spent_time := OS.get_ticks_msec() - start_time
	var sleep_time = (MIN_TIME - spent_time) as float / 1000.0

with error message:

Godot 3.5 beta3, the same issue reproducible with different MRP.
Release build has problem with type inference in line var err := file.open("user://save_game.dat", File.READ)

I noticed it with different method calls too. Like trying to infer the Array type returned from intersect_point.

I assume this might also be reproducible in 3.5 beta 2, but not in beta 1?
This is likely a regression from #57851.

Can confirm that 3.5 beta 1 does not have this problem.

Fixed by #59793.
