- implements `airSlice`, `airBitAnd`, `airBitOr`, `airShr`.
- got a basic design going for the `airErrorName` but for some reason it simply returns
empty bytes. will investigate further.
- only generating `.got.zig` entries when not compiling an object or shared library
- reduced the total amount of ops a mnemonic can have to 3, simplifying the logic
Storing defers this way has the benefits that the defer doesn't get
analyzed multiple times in AstGen, it takes up less space, and it
makes Sema aware of defers allowing for 'unreachable else prong'
error on error sets in generic code.
The disadvantage is that it is a bit more complex and errdefers with
payloads now emit a placeholder instruction (but those are rare).

Master branch added `try` to a bunch of testing function calls, and some
lines also had changed how to refer to the native architecture and other
`@import("builtin")` stuff.
