Fix closed over variables not available in debuginfo for Windows MSVC
The issue was that the resulting debuginfo was too complex for LLVM to translate into CodeView records correctly. As a result, it simply ignored the debuginfo which meant Windows debuggers could not display any closed over variables when stepping inside a closure. This fixes that by spilling additional variables to the stack so that the resulting debuginfo is simple (just `*my_variable.dbg.spill`) and LLVM can generate the correct CV records.
