Owen Anderson cc54e76cc6 Fix an issue where a use might be selected before a def, and then we didn't respect the pre-chosen vreg 
assignment when selecting the def.  This is the naive solution to the problem: insert a copy to the pre-chosen
vreg.  Other solutions might be preferable, such as:
  1) Passing the dest reg into FastEmit_.  However, this would require the higher level code to know about reg classes, which they don't currently.
  2) Selecting blocks in reverse postorder.  This has some compile time cost for computing the order, and we'd need to measure its impact.
