Comment at: lib/Analysis/ValueTracking.cpp:3217
     return true;
+  //TODO: Div, rem and shifts can probably be smarter about non-constant values,
+  //and use known bits.

This is really inconsistent, both are used.

%%%lib$ grep -R "// TODO" | wc -l
984
lib$ grep -R "// FIXME" | wc -l
2213

We do consistently have a space after the // , though.
I'll change to "// FIXME:" to match the leading style. :-)
