New issues in Oscat

[ghaith]

Describe the bug
Seems like oscat does not build anymore, one of the issues has to do with constant resolution/propagation (#504)
Another issue is Cannot cast from VOID to DATE_AND_TIME
I also noticed that builtins are not behaving correctly, but since they are not committed yet we can fix them while in progress
I think we should add building oscat as a build step here or in the standard lib so we can track the progress better.

I also noticed that if we replace the std stubs with the real functions, oscat uses a lot of INT types as bits, which our generic resolver complains about for functions like SHR/SHL which expect ANY_BIT instead of ANY_INT.
I don't think this has any effect on compilation though.

Oscat can now compile, the only issues are with pointer sizes
