test: Change llvm_targets to actually emit an object for each target.

Browse source 
Without doing this, we don't actually test whether the data layout string we
generate matches LLVM's.

A number of targets had to be commented out due to this change:

* Some are using a non-working experimental LLVM backend (arc, csky, ...).
* Some don't have working LLD support (lanai, sparc, ...).
* Some don't have working self-hosted linker support (nvptx).
* Some are using ABIs that haven't been standardized (loongarch32).

Finally, all non-x86 uefi targets are hopelessly broken and can't really be
fixed until we change our emit logic to lower *-uefi-* verbatim rather than to
*-windows-*. See: https://github.com/ziglang/zig/issues/21630
