Issue Description:
Try to compile the attached main.swift file. It's a plain Swift file whit two simple lines of code, and opened in Xcode it looks fine. But, it has a standard UTF-8 header marker, with the first three bytes of the file reading EF BB BF.
This causes the Swift compiler to not build the file, instead emitting these "unexpected" errors:
main.swift:1:10: Consecutive statements on a line must be separated by ';'
main.swift:1:1: Use of unresolved identifier 'import'
main.swift:1:11: Use of unresolved identifier 'Foundation'
This is not an issue when only working in Xcode, but it causes problems when editing source files with other editors or IDEs that write such a header — which is perfectly legitimate.
By contrast, Clang/LLVM will compile ObjC .h/.m files with such a header just fine.
Attached: a project that illustrates the issue, as well as two screenshots showing (a) the errors emitted in Xcode and (b) the content ion the file in a hex viewer.
