 convenience method.  Fix typo in comment.
lib/Target/X86/InstSelectSimple.cpp: Explicitly specify some implicit uses.

both totals and the average is their ratio).

Fix two bugs:
 * The globals vector was getting broken and unsorted, this caused vortex
   to get badly pessimized
 * Node offset handling was being handled really poorly, and in particular
   we were not merging types with offsets right.  This causes several graphs
   to be non-merged.
