failing when encountering windows directory separators.
Fix the path separator platform issue with a FileCheck pattern {{[/\\]}}
Original commit message:
A followup to the feature added in 69da27c749
that added the optional "start file name" to match "start line" - but this
didn't work with Split DWARF because of the need for the decl file number
resolution code to refer back to the skeleton unit to find its .debug_line
contribution. So this patch adds the necessary infrastructure to track the
skeleton unit corresponding to a split full unit for the purpose of this
lookup.
