Sometimes the clang driver will receive a target triple where the deployment version is too low to support the platform + arch. In those cases, the compiler upgrades the final minOS which is what gets recorded ultimately by the linker in LC_BUILD_VERSION. TextAPI should also reuse this logic for capturing minOS in recorded TBDv5 files. Reviewed By: ributzka Differential Revision: https://reviews.llvm.org/D145690
