## Message

```
C backend: cleanups to wrapping int operations

 * less branching by passing parameters in the main op code switch.
 * properly pass the target when asking the type system for int info.
 * handle u8, i16, etc when it is represented using
   int_unsigned/int_signed tag.
 * compile error instead of assertion failure for unimplemented cases
   (greater than 64 bits integer).
 * control flow cleanups
 * zig.h: expand macros into inline functions
 * reduce the complexity of the test case by making it one test case
   that calls multiple functions. Also fix the problem of c_int max
   value mismatch between host and target.

```
