Reid Kleckner ca4ed882f4 Reland "Use Clang's __has_* macros in Compiler.h ..." with fixes ... This reverts r185841 and relands r185831 without using __has_attribute(const). Clang prior to r161767 (between 3.1 and 3.2) does not accept __has_attribute(const) due to rdar://10253857. __const and __const__ are both keyword aliases of const, so they don't work either. I was able to repro the buildbot failure using clang 3.1 and this patch fixes it. Various important versions of XCode use clang 2.9-ish, so this workaround is necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185850 91177308-0d34-0410-b5e6-96231b3b80d8		2013-07-08 19:06:25 +00:00
