Richard Trieu 74973037eb Catch more cases with -Wenum-compare 
Treat typedef enum as named enums instead of anonymous enums.  Anonymous enums
are ignored by the warning, so previously, typedef enums were ignored as well.

Chandler Carruth 543cb655b1 Implement -Wenum-compare, which warns when comparing two enums of 
different types. We omit the warning when the enum types are anonymous.
Unlike GCC, this warning does not distinguish between C++ and C/ObjC for
controling whether it is on by default, it is always on by default.

Original patch contributed by Richard Trieu (@ Google), I fixed some
style issues, and cleaned it up for submission.
