Several times in the JVM interpreter and compile chain the immediate value 0 is loaded in a register in order to be used in some calculation. Performance can be improved if the zero value is kept cached in a register and left untouched, hence it can be used anytime when a 0 value is necessary. As PPC64 has many registers, this change doesn't increase spill pressure because there are still many registers available.
