Subject: [PATCH] Fix bug with multiple EmitCode() calls due to missing braces.

In short, we were inadvertently trying to emit each function's
code a second time if the function had a mask check at the start
of it.  StmtList::EmitCode() was covering this error up by
not emitting code if the current basic block is NULL.
