tgsi: use X component of the second operand in exec_scalar_binary() 

The code happened to work in the past since the (scalar) src args
effectively always have a swizzle of .xxxx, .yyyy, .zzzz, or .wwww so
whether you grab the X or Y component doesn't really matter.  Just
fixing the code to make it look right.
