[ELF][ARM] Add test case that will fail if toPlt() is removed [NFC] When a thunk is created to a PLT entry, the call to the thunk is converted to a non-plt expression with fromPlt(). If the thunk becomes unusable we retarget the relocation back to its original target and try again. When we do this we need to make sure that we restore the PLT form of the expression with toPlt(). This change adds a test case that will fail if toPlt() is removed. We need to have a call to a preemptible symbol defined within the link unit. If toPlt() is removed then the relocation to the thunk to the PLT entry for the preemptible symbol will be retargeted to the preemptible symbol itself instead of its PLT entry.
