is currently off by default, and can be enabled with
-disable-post-RA-scheduler=false.

This doesn't have a significant impact on most code yet because it doesn't
yet do anything to address anti-dependencies and it doesn't attempt to
disambiguate memory references. Also, several popular targets
don't have pipeline descriptions yet.

The majority of the changes here are splitting the SelectionDAG-specific
code out of ScheduleDAG, so that ScheduleDAG can be moved to
libLLVMCodeGen.a. The interface between ScheduleDAG-using code and
the rest of the scheduling code is somewhat rough and will evolve.

being called to be converted to a reference-to-function,
pointer-to-function, or reference-to-pointer-to-function. This is done
through "surrogate" candidate functions that model the conversions
from the object to the function (reference/pointer) and the
conversions in the arguments.

Use PreprocessorLexer::getFileID() instead of Lexer::getFileLoc().  This is an intermediate step to having getCurrentLexer() return a PreprocessorLexer* instead of a Lexer*.

- Add variants of IsNonPragmaNonMacroLexer to accept an IncludeMacroStack entry
  (simplifies some uses).
- Use IsNonPragmaNonMacroLexer in Preprocessor::LookupFile.
- Add 'FileID' to PreprocessorLexer, and have Preprocessor query this fileid
  when looking up the FileEntry for a file

Performance testing of -Eonly on Cocoa.h shows no performance regression because

with function call syntax, e.g.,

  Functor f;
  f(x, y);

This is the easy part of handling calls to objects of class type 
(C++ [over.call.object]). The hard part (coping with conversions from
f to function pointer or reference types) will come later. Nobody uses
that stuff anyway, right? :)

Do not use separate utility to walk all instructions and remove dead dbg intrinsics. Let instcombiner do this job.

If there are two consecutive llvm.dbg.stoppoint calls then
it is likely that the optimizer deleted code in between these
two intrinsics. Keep only the last llvm.dbg.stoppoint in this case.

};

Introduce DeclContext::getLexicalParent which may be different from DeclContext::getParent when nested-names are involved, e.g:

   namespace A {
      struct S;
   }
   struct A::S {}; // getParent() == namespace 'A'
                   // getLexicalParent() == translation unit
