[driver][darwin] Pass -platform_version flag to the linker instead of the -<platform>_version_min flag In Xcode 11, ld added a new flag called -platform_version that can be used instead of the old -<platform>_version_min flags. The new flag allows Clang to pass the SDK version from the driver to the linker. This patch adopts the new -platform_version flag in Clang, and starts using it by default, unless a linker version < 520 is passed to the driver.

[clang+lld] Pass -platform_version args to ld64.lld Fix regression where we aren't passing `-platform_version` to new ld64.lld after {D95204}. Most of the changes were originally in D95204, but I backed them out due to test failures on builds which have `CLANG_DEFAULT_LINKER=lld`. The tests are properly updated in this diff.

clang: Pass -platform-version to new MachO LLD New MachO LLD doesn't implement the old -macos_version_min (etc) flags, but it understands the modern platform_version flag. So make the clang driver pass that when using new MachO LLD. Also, while here, don't pass -lto_library to LLD, since it links in LTO libraries statically (which it can because it's versioned alongside clang).

[driver][darwin] Don't use -platform_version flag by default (PR44813) The code in llvmorg-10-init-12188-g25ce33a6e4f is a breaking change for users of older linkers who don't pass a version parameter, which prevents a drop-in clang upgrade. Old tools can't know about what future tools will do, so as a general principle the burden should be new tools to be compatible by default. Also, for comparison, none of the other tests of Version within AddLinkArgs add any new behaviors unless the version is explicitly specified. Therefore, this patch changes the -platform_version behavior from opt-out to opt-in. Patch by David Major! Differential revision: https://reviews.llvm.org/D74784
