Revert "Rollup merge of #87779 - Aaron1011:stmt-ast-id, r=petrochenkov"

Fixes #87877

This change interacts badly with `noop_flat_map_stmt`,
which synthesizes multiple statements with the same `NodeId`.

I'm working on a better fix that will still allow us to
remove this special case. For now, let's revert the change
to fix the ICE.

This reverts commit a4262cc984, reversing
changes made to 8ee962f88e.
