BUG: unhandled primitive in codegen: slice_literal

[BlobCodes]

Bug Report

The following code results in a compiler bug:

a = Slice(UInt8).literal(0)
b = Slice(UInt8).literal(1)

This only happens when both variables are not constants (or if there is no assignment at all) and if both literals have the same amount of elements.
This also doesn't happen if the two literals have different types (ex. Slice(UInt32) and Slice(UInt8)).

Stack trace:
