Issue Description:

I was using the January, 27 toolchain from snapshots on Windows 10. I can compile a simple executable, but source list LLDB command does not list any source location. It makes not possible to set any breakpoint in the code and stops us from having the working debugger on Windows in the CLion (and I believe, in any IDE that needs to debug Swift on Windows). Related issue is here.

Quality of debug info is still an issue. The proper thing to do is to improve CodeView emission and get that fully covered.

I ran into the same issue after trying to use CodeLLDB in Visual Studio Code on Windows (vadimcn/codelldb#566

I've noticed that when compiling in release mode, I can set breakpoints. However, without the Swift-specific LLDB, the variable names are mangled.

Hello, have there has been any updates to lldb working properly in debug configuration? Still can only set source file line breakpoints in release configuration. I've been using release config with -Onone to debug, but I'd like to learn any better ways.

Thanks!
