Add support for alignment-specifiers in C1X and C++11, remove support for the C++0x draft [[align]] attribute and add the C1X standard header file stdalign.h llvm-svn: 140796 2011-09-30 02:04:28 +08:00			`/*===---- stdalign.h - Standard header for alignment ------------------------===`

Move the builtin headers to use the new license file header. Summary: These all had somewhat custom file headers with different text from the ones I searched for previously, and so I missed them. Thanks to Hal and Kristina and others who prompted me to fix this, and sorry it took so long.

libstdc++'s <cstdalign> #includes <stdalign.h> and expects it to guard against being included in C++. Don't define alignof or alignas in this case. Note that the C++11 standard is broken in various ways here (it refers to the contents of <stdalign.h> in C99, where that header did not exist, and doesn't mention the alignas macro at all), but we do our best to do what it intended. llvm-svn: 175708 2013-02-21 10:17:58 +08:00			`#ifndef __cplusplus`
