RFR: 8328633: s390x: Improve vectorization of Match.sqrt() on floats

[Sidraya Jayagond]

[JDK-8190800](https://bugs.openjdk.org/browse/JDK-8190800) added `VSqrtF` and `SqrtF` nodes to support the vectorization of Match.sqrt() on floats. For s390x port, however, the scalar version of `sqrtF` still uses the old match rule that converts Float to Double first. It can be simplified to just use `SqrtF`.

The old match rule also affects the vectorization of Math.sqrt() on float.
