Improve insn selection for helper calls. Attempt to evaluate arguments into the real register that is mandated by the ABI instead of evaluating it in a virtual register and then move the result. Observed savings in insns between 0.5% and 1.4%. Probably an overrated optimization given current helper functions which rarely take more than one argument. git-svn-id: svn://svn.valgrind.org/vex/trunk@2326 8f6e269a-dfd6-0310-a8e1-e2731360e62c
