On ppc64le, functions compiled with -shared expect r12 to hold the function's address for indirect calls. Previously this was enforced by generating a move instruction if the address wasn't already in r12. This change avoids that extra move by requesting r12 in the CALL ops that do indirect calls. As a result of adding support for plugins on ppc64le, it was discovered that there would be more cases where this extra move was needed, so this seemed like a better solution.
