AArch64 code generator incorrectly encodes `smulh` and `umulh` instructions, and those malformed instructions produce unexpected results. This commit fixes encoding of those instructions and adds binary encoding unit tests. Issue eclipse-openj9/openj9#18057 Signed-off-by: Akira Saitoh <saiaki@jp.ibm.com>
