Teach the NCG about the dereferencing and naming conventions to be used when compiling for a DLLised world. Some cleanups on the way too. The scheme is that * All CLabels which are in different DLLs from the current module will, via the renamer, already be such that labelDynamic returns True for them. * Redo the StixPrim/StixMacro stuff so that all references to symbols in the RTS are via CLabels. That means that the usual labelDynamic story can be used. * When a label is printed in PprMach, labelDynamic is consulted, to generate the __imp_ prefix if necessary. * In MachCode.stmt2Instrs, selectively ask derefDLL to walk trees before code generation and insert deferencing code around other-DLL symbols. * When generating Stix for SRTs, add 1 to other-DLL refs. * When generating static closures, insert a zero word before the _closure label.
