two MD5 tests fail "RuntimeException: Unexpected count of intrinsic"

The following two test fail in the JDK16 CI:

compiler/intrinsics/sha/sanity/TestMD5MultiBlockIntrinsics.java
compiler/intrinsics/sha/sanity/TestMD5Intrinsics.java

Here's a snippet from the TestMD5MultiBlockIntrinsics.java log file:

Even though these are Tier6 failures, I'm starting this as
a P2 since it looks like a regression due to a recent change.
