Rename SymbolID to SymbolRef.  This is a precursor to some overhauling of the representation of symbolic values.

StoreManager::Retrieve and StoreManager::RemoveDeadBindings now take a GRState* argument instead of a Store.  This allows them to use the GDM for storing other data.

method to check to see if we're in a function or objc method.
Minor cleanups to other related places.  This fixes rdar://6405429.

Add a -fblocks option that allows the user to override the target's default.
Use -fblocks in the various testcases that use blocks.

- Implement RewritePropertySetter(). While the routine is simple, there were some tricky changes to RewriteFunctionBodyOrGlobalInitializer(), the main rewriter loop. It also required some additional instance data to distinguish setters from getters, as well as some changes to RewritePropertyGetter().

- Implement FIXME: for pretty printing ObjCPropertyRefExpr's.

- Changed ObjCPropertyRefExpr::getSourceRange() to point to the end of the property name (not the beginning). Also made a minor name change from "Loc"->"IdLoc" (to make it clear the Loc does not point to the ".").

Revamp RegionStoreManager::RemoveDeadBindings.  This method now does a complete mark-and-sweep of the store, removing dead regions and recording the set of live and dead symbols appropriately.

Correct CodeGen assumption that LongTy == Int32Ty in a few places. This makes several CodeGenObjC tests pass on 64-bit by fixing assertions. This doesn't mean that the result is actually what the GNU runtime expects, though.

Fix some type punning errors in SizeOfAlignOf and Typeid AST nodes. This should satisfy compilers and language lawyers alike.

- Fix nonsensical logic in AssumeSymGE. When comparing 'sym >= constant' and the
  constant is the maximum integer value, add the constraint that 'sym ==
  constant' when the path is deemed feasible.  All other cases are feasible.
- Improve AssumeSymGT. When comparing 'sym > constant' and constant is the
  maximum integer value we know the path is infeasible.
- Add test case for this enhancement to AssumeSymGT.

- Fix nonsensical logic in AssumeSymLE. When comparing 'sym <= constant' and the
  constant is the minimum integer value, add the constraint that 'sym ==
  constant' when the path is deemed feasible.  All other cases are feasible.
- Improve AssumeSymLT to address <rdar://problem/6407949>.  When comparing
  'sym < constant' and constant is the minimum integer value we know the
  path is infeasible.
- Add test case for <rdar://problem/6407949>.

Use an array instead of a DenseMap to cache persistent IDs -> IdentifierInfo*.  This leads to a 4% speedup at -fsyntax-only using PTH.

- Remove PTHManager.cpp.  Move all of its functions to PTHLexer.cpp since some of the internal methods are used by PTHLexer (their implementations are intertwined.)  This enables some important inlining opportunities at -O3.

- Don't construct an std::vector<Token> prior to feeding PTH tokens to the Preprocessor.  Stream them off the PTH file directly.

- Added method "setPTHManager" that will be called by the driver to install
  a PTHManager for the Preprocessor.
- Fixed some comments.
- Added EnterSourceFileWithPTH to mirror EnterSourceFileWithLexer.

llvm-svn: 60437

Added PTHManager, a utility class that will be used by Preprocessor to lazily create PTHLexer objects for pre-tokenized files.
