Eli Friedman a1b4ed8003 Implementation of __builtin_shufflevector, a portable builtin capable of
expressing the full flexibility of the LLVM shufflevector instruction.  
The expected immediate usage is in *mmintrin.h, so that they don't 
depend on the mess of gcc-inherited (and not completely implemented)
shuffle builtins.

Argyrios Kyrtzidis fa8e15bfa5 -Implement proper name lookup for namespaces.
-identifierResolver exposes an iterator interface to get all decls through the scope chain.
-The semantic staff (checking IdentifierNamespace and Doug's checking for shadowed tags were moved out of IdentifierResolver and back into Sema. IdentifierResolver just gives an iterator for all reachable decls of an identifier.

Nate Begeman f322eabbce Extend vector member references to include {.hi, .lo, .e, .o} which return a
vector of the same element type and half the width, with the high, low, even,
and odd elements respectively.

Allow member references to member references, so that .hi.hi gives you the high
quarter of a vector.  This is fairly convenient syntax for some insert/extract
operations.

Remove some unnecessary methods/types in the ExtVectorElementExpr class.

Ted Kremenek f958ec50c0 Expand the CF retain checker to allow the Create/Get rule to apply to any
function that returns a CFxxxRef, not just functions whose name begins with
CF.  This implements <rdar://problem/5917879>.

Added test case for this feature.

Updated calls to CStrInCStrNoCase to swap their arguments, per compatibility
with strcasestr.

Ted Kremenek 015c3561ad Use EvalSummary to process message expressions, thereby unifying the checker
logic for function calls and message expressions.

Use the following heuristic to infer "allocating" instance methods:

  [ClassName classWithXXX]  allocates an object

Chris Lattner 73669defed remove the 'unused static' diagnostic from codegen. This should be
reimplemented in Sema someday.  This is tracked in PR2236.  Until then
disabling it removes some bogus diagnostics (see 2236).

Ted Kremenek ecbdf75049 Do a better job at computing dead symbols.
Implemented support for better localized leaks in the CF reference count checker.
