Description of Problem:
CS0172 incorrectly reported for a pair of types when one can be implicitly
promoted to the other.

Steps to reproduce the problem:
Compile the following two lines of C# code:
byte x = 4;
byte a = (byte)(true ? x : 0);


Actual Results:
CS0172 reported on the second line.

Expected Results:
Code should compile.  This compiles correctly with MS's C# compiler.  The byte
type (x variable) should be promoted to an integer, so that both types in the
conditional are the same.

How often does this happen? 
Every time.
