This patch changes relative path for source files in obj files to absolute path in PDB when linking with added flag. I will make obj file generated by clang-cl independent from build directory for chromium build. But I don't want to confuse visual studio debugger or require additional configuration. To attain this goal, I added flag to convert relative source file path in obj to absolute path when emitting PDB. By removing absolute path from obj files, we can share build cache between chromium developers even when they are doing debug build. That will make build time faster.
