<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Small optimization to CmmSink.
Inside `regsUsedIn` we can avoid some thunks by specializing the
recursion. In particular we avoid the thunk for `(f e z)` in the
MachOp/Load branches, where we know this will evaluate to z.
Reduces allocations for T3294 by ~1%.

No user-facing names are changed.
