[PATCH] D60399: [CMake] Replace LLVM_ENABLE_CXX1Y and friends with LLVM_CXX_STD

[Petr Hosek via Phabricator via llvm-commits]

This broke all our builders that use the LLVM runtimes build with the following error:

  -- Performing Test CXX_SUPPORTS_CXX_STD
  -- Performing Test CXX_SUPPORTS_CXX_STD - Failed
  CMake Error at /b/s/w/ir/k/llvm-project/llvm/cmake/modules/HandleLLVMOptions.cmake:451 (message):
    The host compiler does not support '-std='.
  Call Stack (most recent call first):
    CMakeLists.txt:111 (include)
  
  
  -- Configuring incomplete, errors occurred!

The full log is here: https://logs.chromium.org/logs/fuchsia/buildbucket/cr-buildbucket.appspot.com/8916679531057446976/+/steps/clang/0/steps/build/0/stdout

I suspect it's because we include `HandleLLVMOptions` at https://github.com/llvm/llvm-project/blob/master/llvm/runtimes/CMakeLists.txt#L111, but at that point we haven't yet compiled libc++, so any attempt to use is going to fail which is why this check is failing.
