Mixed-source targets generally include the generated <Product>-Swift.h header in many Objective-C (.m) source files. Any change to a Swift file results in the header being touched, which means all the .m files get recompiled. This change makes Swift write the generated header to a temporary file first, then use the previous commit's moveFileIfDifferent to put it in its final destination. rdar://problem/20553459 Swift SVN r28042
