Modified Files:
	src/sys/vm: vm_map.h
Log Message:
remove the following if UVM is defined:
- share_map in vm_map_object.   UVM doesn't use share maps, so drop unused
partial support for them to simplify the code.
- is_main_map in vm_map.   no longer needed once share maps are gone.
- vm_map_version_t.   map versions are handled elsewhere in UVM.
