[LLVMdev] Do we still need LLVM_HAS_INITIALIZER_LISTS?

[Justin Bogner]

Currently, LLVM_HAS_INITIALIZER_LISTS is set based on

  __has_feature(cxx_generalized_initializers) && !defined(_MSC_VER)

Based on the docs, we should be able to drop the _MSC_VER check now that
we've moved to VS2013. Can somebody confirm that?

The other problem is that GCC doesn't recognize __has_feature, so this
is essentially only enabled for clang. If we're keeping this check it
should really check the GCC version as well - they've had these for
quite a while now.
