* AIR: add `mod` instruction for modulus division - Implement for LLVM backend * Sema: implement `@mod`, `@rem`, and `%`. * Sema: fix comptime switch evaluation * Sema: implement comptime shift left * Sema: fix the logic inside analyzeArithmetic to handle all the nuances between the different mathematical operations. - Implement comptime wrapping operations
