P0188R1: add support for standard [[fallthrough]] attribute. This is almost exactly the same as clang's existing [[clang::fallthrough]] attribute, which has been updated to have the same semantics. The one significant difference is that [[fallthrough]] is ill-formed if it's not used immediately before a switch label (even when -Wimplicit-fallthrough is disabled). To support that, we now build a CFG of any function that uses a '[[fallthrough]];' statement to check. In passing, fix some bugs with our support for statement attributes -- in particular, diagnose their use on declarations, rather than asserting. llvm-svn: 262881

Sema: diagnose use of unscoped deprecated prior to C++14 The deprecated attribute was adopted as part of the C++14, however, there is a GNU version available in C++11. When using C++ earlier than C++14, diagnose the use of the attribute without the GNU scope, but only when using the generalised attribute syntax. llvm-svn: 229447

// NOTE: use -Wno-deprecated to avoid cluttering the output with deprecated

[[deprecated("1")]] int function_1();
Minor tweaks to r229447 to ensure the attribute is properly quoted when diagnosed. llvm-svn: 229454
