[Clang] Harmonize Split DWARF options with llc Summary: With Split DWARF the resulting object file (then called skeleton CU) contains the file name of another ("DWO") file with the debug info. This can be a problem for remote compilation, as it will contain the name of the file on the compilation server, not on the client. To use Split DWARF with remote compilation, one needs to either * make sure only relative paths are used, and mirror the build directory structure of the client on the server, * inject the desired file name on the client directly. Since llc already supports the latter solution, we're just copying that over. We allow setting the actual output filename separately from the value of the DW_AT_[GNU_]dwo_name attribute in the skeleton CU. Fixes PR40276.
