Chris Lattner 091f698d29 "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."

Chris Lattner 5a92bab4f0 "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.

Chris Lattner 552b52f49d "This maps the -pthread option to -lpthread - this isn't 100% correct,
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."

Dan Gohman e6e1348275 Change ScheduleDAG's SUnitMap from DenseMap<SDNode*, vector<SUnit*> >
to DenseMap<SDNode*, SUnit*>, and adjust the way cloned SUnit nodes are
handled so that only the original node needs to be in the map.
This speeds up llc on 447.dealII.llvm.bc by about 2%.

Ted Kremenek 34a691734e Modified the dead stores checker to...
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.
   
   This addresses the feature request in the following email:

Evan Cheng efc67e78d7 Enhanced heuristic to determine the *best* register to spill. Instead of picking the register with the lowest spill weight. Consider (up to) 2 additional registers with spill weights that are close to the lowest spill weight. The one with fewest defs and uses that conflicts with the current interval (weighted by loop depth) is the spill candidate.
This is not always a win, but there are much more wins than loses and wins tend to be more noticeable.

Ted Kremenek d50c7a4b0d 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.
