[PATCH] Support Android NDK (which has neither futimes nor futimens)

[Neil Henning]

  As per the discussion on the llvm-commits mailing list - I've simplified the fix.

  I've taken Alp Toker's approach but removed all mention of ANDROID from the patch, instead allowing setLastModificationAndAccessTime to gracefully fail at runtime should a platform not have support for futimes or futimens.
