[11u] RFR 8211296: Remove HotSpot deprecation warning suppression for Mac/clang

[Vladimir Kempik]

Hello
Please review this backport of JDK-8211296 to jdk11u

The patch didn’t apply cleanly. Part of changes (for CompileJvm.gmk file) wasn’t needed.

The motivation behind this backport is to prepare for aarch64 macos, finite macro is missing there and needs to be replaced with isfinite.

Testing: tier1.

The bug: https://bugs.openjdk.java.net/browse/JDK-8211296
