[Preprocessor] Prevent expansion of y in x ## y when x is empty
When x is empty, x ## is suppressed, and when y gets expanded, the fact that it follows ## is not
available in the macro expansion result. The macro definition can be checked instead, the ## will
be available there regardless of what x expands to.
Fixes http://llvm.org/PR12767
Patch by Harald van Dijk!
