Bug 1265624 - Remove unnecessary compiler version check for MSVS 2010 in nsFrameState.h. r=heycam

- * Visual Studio 2010 has trouble with the sized enum.  Although sized enums
- * are supported, two problems arise:
- *
- *   1. Implicit conversions from the enum type to the equivalently sized
- *      integer size are not performed, leading to many compile errors.
- *   2. Even with explicit casts added to avoid the errors from (1), odd
- *      test failures result, which might well be due to a compiler bug.
- *
- * So with VS2010 we use consts for the state bits and forgo the increased
- * type safety of the enum.  (Visual Studio 2012 has no problem with
- * nsFrameState being a sized enum, however.)
