- Kill unnecessary #includes in .cpp files. This is an automatic
   sweep so some things removed are actually used, but happen to be
   included by a previous header. I tried to get rid of the obvious
   examples and this was the easiest way to trim the #includes in one
   fell swoop.
 - We now return to regularly scheduled development.

 - Drop {Decl.h,DeclObjC.h,IdentifierTable.h} from Expr.h
 - Moved Sema::getCurMethodDecl() out of line (dependent on
   ObjCMethodDecl via dyn_cast).

llvm-svn: 54629

 - Remove internal uses of AST.h

llvm-svn: 54628

 - Drop Expr.h,RecordLayout.h from ASTContext.h (for DeclBase.h and
   SourceLocation.h)
 - Move ASTContext constructor into implementation

llvm-svn: 54627

 - Drop Diagnostic.h from DeclSpec.h, move utility Diag methods into
   implementation .cpp

llvm-svn: 54626

 - Drop TokenKinds.h from Action.h
 - Move DeclSpec.h from Sema.h into individual Sema .cpp files

  temporarily, I assumed GetAddrForConstantString literal was being
  used consistently but it doesn't look like it is.

Factored out a CodeGenModule::getStringForStringLiteral which handles
  extracting a std::string for the bytes of a StringLiteral, padded to
  match the type.

Update EmitLValue to use getStringForStringLiteral, this was
  previously not padding strings correctly. Good thing we only emit
  strings in 4 different places!

* Move FormatError() from TextDiagnostic up to DiagClient, remove now  
  empty class TextDiagnostic
* Make DiagClient optional for Diagnostic

This fixes the following problems:

* -html-diags (and probably others) does now output the same set of  
  warnings as console clang does
* nothing crashes if one forgets to call setHeaderSearch() on  
  TextDiagnostic
* some code duplication is removed

InitListChecker::CheckListElementTypes(): Check for function types and issue an appropriate diagnostic.

Cleanup from yesterday...make isTentativeDefinition() a static helper function (no need for it to be part of the Sema API).

llvm-svn: 54613

Sema::CheckForFileScopedRedefinitions(): Make sure tentative decls of incomplete array types are completed (and diagnosed properly).

llvm-svn: 54612

Allow the preprocessor to cache the lexed tokens, so that we can do efficient lookahead and backtracking.

1) New public methods added:
  -EnableBacktrackAtThisPos
  -DisableBacktrack
  -Backtrack
  -isBacktrackEnabled

2) LookAhead() implementation is replaced with a more efficient one.
3) LookNext() is removed.

member count.  The count returned by numStructUnionElements is the 
number of initializers that will be consumed, not the number of members 
to iterate through.  Fixes PR2534.

Fix Sema::MergeVarDecl() to better handle type compatibility. The previous code was trying to handle arrays specially (which didn't work for pointers to array). Removed local helper function areEquivalentArrayTypes(), replacing it's use with the more general ASTContext::typesAreCompatible() predicate.

Even though the test case this fixes is in "tentative-decls.c", this bug didn't have anything to do with our handling of tentative definitions (which is what I first expected). In any event, this is a tricky area of the spec.

Passing right brace location to ActOnFinishCXXClassDef is redundant, since it gets passed to ActOnFinishCXXMemberSpecification too.

- Move checking from MergeVarDecl->FinializeDeclaratorGroup. Since MergeVarDecl is called before the initializer is attacted, it can't be done there (this removes a long standing FIXME).
- Add Sema::isTentativeDefinition() and Sema::CheckForFileScopedRedefinitions().
- Remove FIXME's and touch-up test case.

Still some more work to do (forthcoming)...

The motivation is that clients may either:

(a) query the ASTConsumer object after AST parsing to collect data/etc.
(b) reuse the ASTConsumer.
