  Changed paths:
    M clang/lib/Driver/SanitizerArgs.cpp
    M clang/lib/Driver/ToolChains/CommonArgs.cpp
    M clang/test/Driver/sanitizer-ld.c

  Log Message:
  -----------
  [Driver] -fsanitize=numerical: work with ubsan and support -shared-libsan

* `-fsanitize=numerical,undefined`: don't link in the ubsan standalone
  runtime.
* `-shared-libsan`: link against `libclang_rt.nsan.so`

The compiler-rt part will be properly fixed by #98415
