'There's not much to say about this patch, it just adds the Arch Linux
gcc 4.3.1 header paths for i686 and amd64. The patch was generated
using "svn diff" with clang at revision 52660. The paths aren't
distribution-specific, so they should work for all Linux distributions
using the default(?) names like "i686-pc-linux-gnu".'

Added ObjCSummaryCache, a new summary cache object to cache summaries for Objective-C methods.  Instead of mapping from Selectors -> Summaries, we will now map from (ObjCInterfaceDecl*,Selectors) -> Summaries.  This will allow more nuanced summary generation.  This patch just swaps in the new data structure; the rest of the code works as before by allowing the ObjCInterfaceDecl* to be null.

Rename summary methods for "instance methods" to "class methods" (the names got screwed up).  No functionality change.

The CF retain/release checker now assumes that allocations do not fail.  Eventually we will add a flag to the driver to enable allocation failures (documented as a FIXME).

"this patch adds code generation hooks for Objective-C constant strings.  It also modifies Sema so that Objective-C constant strings are treated as untyped objects if the interface for the constant string class can not be found.  This is consistent with Apple GCC.  I thought it was consistent with GNU GCC, since this was causing failures when trying to compile GNUstep with (GNU) GCC, but it appears that this is not the case when attempting to produce a simple test case to demonstrate it.  Possibly there is a way of making the error go away, but I haven't found out what it is yet."

"This moves built-in Objective-C types up the scope chains to where they can be replaced by versions included from the runtime library's headers."

This makes it ok to use @"foo" without a declaration for NSConstantString.

since handling this correctly is quite complex, and on some platforms  
requires additional -D options and on some implies linking against a  
different libc, but this works better than just ignoring the option.

The other change passes the -x option across to clang, which allows  
compiling .c files as Objective-C and so on.  For some reason a lot of  
configure scripts seem to be under the misguided impression that this  
is a sensible thing to do."

When using the dead-stores checker with the BugReporter class, properly capture the diagnostic associated with a specific warning and emit it.

1) Check if a dead store appears as a subexpression.  For such cases, we emit
   a verbose diagnostic so that users aren't confused.  This addresses:
   
   <rdar://problem/5968508> checker gives misleading report for dead store in loop
   
2) Don't emit a dead store warning when assigning a null value to a pointer.
   This is a common form of defensive programming.  We may wish to make
   this an option to the the checker one day.

Added "Decl::getCodyBody()", a virtual method that returns the root AST node (Stmt*) that the Decl wraps (if any).  Currently this only returns a non-null value for FunctionDecl and ObjCMethodDecl.

Added a new ProgramPoint: PostPurgeDeadSymbols.  This new program point distinguishes between the cases when we just evaluated the transfer function of a Stmt* (PostStmt) or performed a load (PostLoad).  This solves a caching bug observed in a recent bug report.
