Log:
  Merge commit 30588a739 from llvm git (by Erich Keane):
  
    Make target features check work with ctor and dtor-
  
    The problem was reported in PR45468, applying target features to an
    always_inline constructor/destructor runs afoul of GlobalDecl
    construction assert when checking for target-feature compatibility.
  
    The core problem is fixed by using the version of the check that
    takes a FunctionDecl rather than the GlobalDecl. However, while
    writing the test, I discovered that source locations weren't properly
    set for this check on ctors/dtors. This patch also fixes constructors
    and CALLED destructors.
  
    Unfortunately, it doesn't seem too possible to get a meaningful
    source location for a 'cleanup' destructor, so those are still
    'frontend' level errors unfortunately. A fixme was added to the test
    to cover that situation.
  
  This should fix 'Assertion failed: (!isa<CXXConstructorDecl>(D) && "Use
  other ctor with ctor decls!"), function Init, file
  /usr/src/contrib/llvm-project/clang/include/clang/AST/GlobalDecl.h, line
  45' when compiling the security/botan2 port.
