shows up in one of the "embarassing" tests (from the thread on llvmdev
"detailed comparison of generated code size for LLVM and other compilers").

This change was a lot bigger than I originally anticipated; among
other things it requires us storing more information in the CFG to
record what block-level expressions need to be evaluated as lvalues.

The big change is that CFGBlocks no longer contain Stmt*'s by
CFGElements.  Currently CFGElements just wrap Stmt*, but they also
store a bit indicating whether the block-level expression should be
evalauted as an lvalue.  DeclStmts involving the initialization of a
reference require us treating the initialization expression as an
lvalue, even though that information isn't recorded in the AST.
Conceptually this change isn't that complicated, but it required
bubbling up the data through the CFGBuilder, to GRCoreEngine, and
eventually to GRExprEngine.

The addition of CFGElement is also useful for when we want to handle
more control-flow constructs or other data we want to keep in the CFG
that isn't represented well with just a block of statements.

In GRExprEngine, this patch introduces logic for evaluating the
lvalues of references, which currently retrieves the internal "pointer
value" that the reference represents.  EvalLoad does a two stage load
to catch null dereferences involving an invalid reference (although
this could possibly be caught earlier during the initialization of a
reference).

Symbols are currently symbolicated using the reference type, instead
of a pointer type, and special handling is required creating
ElementRegions that layer on SymbolicRegions (see the changes to
RegionStoreManager).

Along the way, the DeadStoresChecker also silences warnings involving
dead stores to references.  This was the original change I introduced
(which I wrote test cases for) that I realized caused GRExprEngine to
crash.

than using its own partial implementation of initialization. 

Switched CheckInitializerTypes over to
InitializedEntity/InitializationKind, to help move us closer to
InitializationSequence.

Added InitializedEntity::getName() to retrieve the name of the entity,
for diagnostics that care about such things.

Implemented support for default initialization in
InitializationSequence.

Clean up the determination of the "source expressions" for an
initialization sequence in InitializationSequence::Perform.

Taught CXXConstructExpr to store more location information.

 - This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

For hi/odd of an odd-length vector, the last component is undefined.  Since
we shuffle with an undef vector, no CodeGen needs to change to support this.

  - During instantiation, drop default arguments from constructor and
    call expressions; they'll be recomputed anyway, and we don't want
    to instantiate them twice.
  - Rewrote the instantiation of variable initializers to cope with
    non-dependent forms properly.

Together, these fix a handful of problems I introduced with the switch
to always rebuild expressions from the source code "as written."
