Nikita Popov 2f448bf509 [X86] Migrate tests to use opaque pointers (NFC)
Test updates were performed using:
https://gist.github.com/nikic/98357b71fd67756b0f064c9517b62a34

These are only the test updates where the test passed without
further modification (which is almost all of them, as the backend
is largely pointer-type agnostic).
