TestIntrinsicsRegStress.java fails on SPARC

    Description

      When trying to backoprt, I noticed that the test from JDK-8307572 fails on SPARC which therefore seems to be affected as well:

      # A fatal error has been detected by the Java Runtime Environment:
      #
      # Internal Error (/workspace/open/src/hotspot/cpu/sparc/register_sparc.hpp:194), pid=1486, tid=13
      # assert(c < 64 && (c & 1) == 0) failed: bad double float register

      Current CompileTask:
      C2: 22011 779 b compiler.c2.aarch64.TestIntrinsicsRegStress::checkCompress (625 bytes)
