make type_allowed_in_extern more robust
Previously if the type parameter was a pointer, it would assert that the
size of the type was resolved. It used to be that the size of pointers was
always resolved, however with lazy values, pointers gained the
possibility of not having their size resolved.

Now, type_allowed_in_extern triggers the resolution of whether a pointer
is zero bits, and returns a possible error if the resolution fails.

This fixes a compiler assertion when building the
[zootdeck project](https://github.com/donpdonp/zootdeck). I do not have
a test case reduction for the issue.

implement runtime @byteSwap and other fixups
* update docs for `@byteSwap`.
 * fix hash & eql functions for ZigLLVMFnIdBswap not updated to
   include vector len. this was causing incorrect bswap function
   being called in unrelated code
 * fix `@byteSwap` behavior tests only testing comptime and not
   runtime operations
 * implement runtime `@byteSwap`
 * fix incorrect logic in ir_render_vector_to_array and
   ir_render_array_to_vector with regards to whether or not to bitcast
 * `@byteSwap` accepts an array operand which it will cast to vector
 * simplify `@byteSwap` semantic analysis code and various fixes

Fix array->vector and vector->array for many types. Allow vector of bool.
Vectors do not have the same packing as arrays, and just bitcasting
is not the correct way to convert them.

fix tripping llvm assert
```
Assertion `!isa<DIType>(Scope) && "shouldn't

We've had this problem and solved it before; see #579.

Force LLVM to generate byte-aligned packed unions
Sometimes the frontend and LLVM would disagree on the ABI alignment of a
packed union. Solve the problem by telling LLVM we're gonna manage the
struct layout by ourselves.

Always resolve the struct field types
Packed structs used to skip the zero-sized types and trip some

improvements to @asyncCall
* `await @asyncCall` generates better code. See #3065
 * `@asyncCall` works with a real `@Frame(func)` in addition to
   a byte slice. Closes #3072
 * `@asyncCall` allows passing `{}` (a void value) as the result
   pointer, which uses the result location inside the frame.
   Closes #3068
 * support `await @asyncCall` on a non-async function. This is in
   preparation for safe recursion (#1006).

```zig

fn Bar(comptime alignment: u29) type {
    return struct {
        field: *align(alignment) Foo,
    };
}
