The unintended behavior exposed by this PR is not due to `HostTriple` being set
incorrectly. It is due to offloading toolchain being constructed unexpectedly.

It looks like `HostTriple` is used only to set type properties. I made the
suggested modifications and added a test to verify it works as expected now.
