tests: restore standalone/ios, add Zig code to it
This was deleted in beef9fdf42726d8cfe3017ff3017767fb615ef08 because it
was setting `b.sysroot`. However, I frankly have no idea why it was
doing that---the test works just fine without touching `b.sysroot`!
Even before it was removed, this test was never actually running,
because the executable was not added as a dependency of `test_step`. I
made it run, and updated it to work (it was previously failing due to a
missing framework path).
I also added some Zig source code, the goal being to test that the panic
handler compiles okay on iOS. I confirmed that the updated test passes
as-is, but fails if the fix in the previous commit is reverted.
Because this test requires the iOS SDK to be installed, it is only run
if `-Denable-ios-sdk` is passed to `zig build`, which is currently not
the case in CI. For now, I am not changing this, because the
aarch64-macos CI runner currently does not have the iOS SDK installed.
It would be good to enable this coverage on CI at some point, though.4 files changed, 86 insertions(+), 0 deletions(-)
