At present, if a write resource is listed more than once by a
instruction, the resource is assumed to be used sequentially
across multiple cycles.  The new ResourceUses attribute
of ProcWriteResource permits multiple simultaneous uses to be
specified.

Use the ResourceUses information when performing machine scheduling
and other codegen tasks.
