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.

struct A {

struct A::B {
  void m() {} // Assertion failed: getContainingDC(DC) == CurContext && "The next DeclContext should be lexically contained in the current one."
};

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

In C++, a comma expression is an lvalue if its right-hand
subexpression is an lvalue. Update Expr::isLvalue accordingly.

The core fix in Sema::ActOnClassMessage(). All the other changes have to do with passing down the SourceLocation for the receiver (to properly position the cursor when producing an error diagnostic).

post-decrement, including support for generating all of the built-in
operator candidates for these operators. 

C++ and C have different rules for the arguments to the builtin unary
'+' and '-'. Implemented both variants in Sema::ActOnUnaryOp.

In C++, pre-increment and pre-decrement return lvalues. Update
Expr::isLvalue accordingly.

An assert is hit:
Assertion failed: CachedTokens[CachedLexPos-1].getLocation() == Tok.getAnnotationEndLoc() && "The annotation should be until the most recent cached token", file ..\..\lib\Lex\PPCaching.cpp, line 98

Introduce Preprocessor::RevertCachedTokens that reverts a specific number of tokens when backtracking is enabled.

llvm-svn: 59636

Remove Preprocessor::CacheTokens boolean data member. The same functionality can be provided by using Preprocessor::isBacktrackEnabled().
