      Reintroduce the InlineHint function attribute. · 74bb06c0

      This time it's for real! I am going to hook this up in the frontends as well.
      
      The inliner has some experimental heuristics for dealing with the inline hint.
      When given a -respect-inlinehint option, functions marked with the inline
      keyword are given a threshold just above the default for -O3.
      
      We need some experiments to determine if that is the right thing to do.

      Introduce new linkage types linkonce_odr, weak_odr, common_odr · 12da8ce3

      and extern_weak_odr.  These are the same as the non-odr versions,
      except that they indicate that the global will only be overridden
      by an *equivalent* global.  In C, a function with weak linkage can
      be overridden by a function which behaves completely differently.
      This means that IP passes have to skip weak functions, since any
      deductions made from the function definition might be wrong, since
      the definition could be replaced by something completely different
      at link time.   This is not allowed in C++, thanks to the ODR
      (One-Definition-Rule): if a function is replaced by another at
      link-time, then the new function must be the same as the original
      function.  If a language knows that a function or other global can
      only be overridden by an equivalent global, it can give it the
      weak_odr linkage type, and the optimizers will understand that it
      is alright to make deductions based on the function body.  The
      code generators on the other hand map weak and weak_odr linkage
      to the same thing.
