Adds examples/1650-platform-asm-rw-place.sx exercising a `+r -> @x`
read-write place output. Currently rejected loudly at lowering
("not yet implemented"); this locks that behavior as a passing test.
The next commit implements read-write outputs and flips this example
to run end-to-end (increment-in-place → 42).
