Incorrect behavior for "self"

[bellcarved]

Describe the bug

Attempting to use "self" as an argument in collision_point will compile as the integer value -1 instead of the assembly code call.i @@this@@(argc=0) like it should, resulting in it always returning false.

Reproducing steps

Create a script of any kind.
Attempt to run a collision check with self as the object (for example, "collision_point(60, 60, self, 0, 0)")
Testing reveals it will always return false.

Setup Details

UndertaleModTool 0.5.1.0
Windows 10
GIMMIKO Demo https://store.steampowered.com/app/2101420/GIMMIKO (should not be relevant to issue, but is where i found the problem when editing a script)

IIRC -1 for self is correct in older GM versions. This might be something that got changed later.

I have the same problem in global scripts where "self" is passed around in functions.

This will likely be fixed with the new compiler, currently entering testing at #2056.
