In walkdiv, an OMUL node was created and passed to typecheck, before the op was changed back to OHMUL. In some instances, the node that came back was an evaluated literal constant that occurred with a full multiply. The end result was a literal node with a non-shifted value and an OHMUL op. This change causes code to be generated for the OHMUL. Fixes #11358 Fixes #11369 Change-Id: If42a98c6830d07fe065d5ca57717704fb8cfbd33 Reviewed-on: https://go-review.googlesource.com/11400 Reviewed-by: Russ Cox <rsc@golang.org>
