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.
