Issue Description:

This code currently produces an error, but shouldn't:

#if false
if $0 { } // error: anonymous closure argument not contained in a closure
#endif

I'm not sure it shouldn't. Code in false branches of ifs still has to parse unless the guard is #if swift or #if compiler. It's fuzzy whether this is a parse error or a semantic error, though.

Comment by Tapan Thaker (JIRA)

Just checked, this is a parse error. Happens at ParseExpr.cpp#L2863.
So does this mean we good to close this issue?

I consider this a bug, because I think the error should come from semantic analysis, not from the parser.
