[PATCH] D134468: [Driver] Ignore -fmsc-version= -fms-compatibility-version= values smaller than 19

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

I am not a Windows driver user. This patch is entirely motivated by Windows discussions in D131465 <https://reviews.llvm.org/D131465> and I want to make `/std:` default rule simple (say, clang 16 uses C++17 for every mode for Windows). If the `-fno-threadsafe-statics` compatibility change is considered too risky, perhaps I'll just change this patch to just do C++17.
