[PATCH] D93375: [clang][driver] Add -ansi option to CompileOnly group

[Timm Bäder via Phabricator via cfe-commits]

That sounds good but it's different to what this patch is trying to accomplish, isn't it? -ansi already doesn't get passed to the linker.
E.g. with clang 10.0.1 without this patch:

  ~ ❯ clang test.o -o test -ansi -###
  clang version 10.0.1 (Fedora 10.0.1-3.fc32)
  Target: x86_64-unknown-linux-gnu
  Thread model: posix
  InstalledDir: /usr/bin
  clang-10: warning: argument unused during compilation: '-ansi' [-Wunused-command-line-argument]
