        Description

        BitSet.nextSetBit() may produce incorrect result in 32bit VM on Sparc.

        countTrailingZerosL() should use iRegIsafe dst register:

        -instruct countTrailingZerosL(iRegI dst, iRegL src, flagsReg cr) %{
        +instruct countTrailingZerosL(iRegIsafe dst, iRegL src, flagsReg cr) %{

        I will add a regression test.
