Subject: Merging r213912:
 ------------------------------------------------------------------------
 r213912 | rtrieu | 2014-07-24 17:24:02 -0700 (Thu, 24 Jul 2014) | 4 lines

Pass the PrintingPolicy when converting types to strings in template type
diffing.  This removes extra "struct"/"class" in the type names and gives
"bool" instead of "_Bool" for booleans.
