4e53249d76 test-cases harness: improve stage2 compatibility 
* proper skip_stage1 mechanism that doesn't get side-stepped with
   manually added test cases.
 * avoid runtime-known function pointers.
 * check for type equality more simply without checking the type name.

ea3db3274d link: avoid passing bad ptrs to pwritev 
At least on Linux, the pwritev syscall checks the pointer and returns
EFAULT before it checks if the length is nonzero.

Perhaps this should be fixed in the standard library, however, these are
still improvements since they make the kernel do less work within the
syscall.

llvm: correctly lower c-abi for Wasm target 
When lowering the return type for Wasm if the calling convention is `C`,
it now correctly lower it according to what clang does as specified in:
https://github.com/WebAssembly/tool-conventions/blob/main/BasicCABI.md

This makes use of the same logic as the Wasm backend, ensuring the
generated code does not diverge in function signatures.

When passing arguments accross the C-ABI for the Wasm target,
we want slightly different behavior than x86_64.
For instance: a struct with multiple fields must always be passed
by reference, even if its ABI size fits in a single integer.
However, we do pass larger integers such as 128bit by value,
which LLVM will correctly lower to use double arguments instead.

wasm: pass correct abi-size for scalar values 
When returning an aggregate type that contains a scalar value (nested),
its abi-size is passed by bits, rather than bytes to `buildOpcode`.

934573fc5d Revert "std.fmt: require specifier for unwrapping ?T and E!T." 
This reverts commit 7cbd586ace46a8e8cebab660ebca3cfc049305d9.

This is causing a fail to build from source:

```
./lib/std/fmt.zig:492:17: error: cannot format optional without a specifier (i.e. {?} or {any})
                @compileError("cannot format optional without a specifier (i.e. {?} or {any})");
                ^
./src/link/MachO/Atom.zig:544:26: note: called from here
                log.debug("  RELA({s}) @ {x} => %{d} in object({d})", .{
                         ^
```

I looked at the code to fix it but none of those args are optionals.
