- This is a fixed version of
https://chromium-review.googlesource.com/c/chromium/src/+/1995743
which was reverted because it caused a build failure for ToTLinux.
-Build failure in ToTLinux is fixed by only adding "--generate-dwp" for
the Android toolchain when building for Android OS.
- Modify some compiler build definitions to allow symbol_level=2 with
Chrome Android 32bit, and to make the build respect use_debug_fission in
those cases.
- Modify "link" and "solink" tools in Android toolchain so that DWP
files can be generated for builds with use_debug_fission.
- Modify partitioned_shared_library template/script so that DWP files
can be generated for partitioned libs when use_debug_fission is set.
