[PATCH] D125862: [clang][driver] Add gcc-toolset/devtoolset 12 to prefixes

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

It may be time to add unittests to `clang/unittests/Driver/ToolChainTest.cpp` for /opt/rh detection. You may use `TEST(ToolChainTest, VFSGCCInstallation)` as an example creating a pseudo file hierarchy in memory.
