ifcpuXX: Support multiple parameters with labels
The ifcpu.c32 and ifcpu64.c32 modules take arguments including the form <true_label> -- <false_label>. It is convenient to allow these labels to be not just a single word, but to include parameters. This is useful for <TAB>-editing and modifying the command-line to include parameters you'd like to pass. Not-yet-tested: Shao Miller <shao.miller@yrdsb.edu.on.ca>
