[jdk11u-dev] RFR: 8252250: isnanf is obsolete

[Aleksei Voitylov]

JDK-8252250 is in the first batch of a chain of backports for Alpine support to 11u as discussed in the mailing list. For the full set of anticipated changes please refer to the jdk-updates mailing list [1].

Unlike original changeset this backport also changes src/java.base/unix/native/libjava/jdk_util_md.h because it also contains isnanf, which was removed in JDK16 by "JDK-8249612: Remove unused ISNANF and ISNAND from jdk_util_md.h" after removing its usage by "JDK-8199424: consider removing ObjectInputStream and ObjectOutputStream native methods" in JDK14.

Testing: JCK + JTreg on Windows, Linux, Solaris, Mac without regressions.
