Chris Lattner e2523b287c when MergeBlockIntoPredecessor merges two blocks, update MemDep if it 
is floating around in the ether.

Chris Lattner f6ae904e34 Fix FoldSingleEntryPHINodes to update memdep and AA when it deletes 
phi nodes.  It is called from MergeBlockIntoPredecessor which is 
called from GVN, which claims to preserve these.

I'm skeptical that this is the actual problem behind PR8954, but
this is a stab in the right direction.

Chris Lattner 63fe78de68 remove a bogus assertion: the latch block of a loop is not 
neccesarily an uncond branch to the header.  This fixes 
PR8955 (the assertion tripping).

Ted Kremenek a00bccc0c5 Rework ExprEngine::processCFGBlockEntrance() 
to use a node builder.  This paves the way
for Checkers to interpose (via a "visit" method)
at the entrance to blocks.

Douglas Gregor aec93c6bbe Ensure that the result type of an Objective-C class message send is 
complete. However, if it returns a reference type, don't require the
type it refers to to be complete. Fixes <rdar://problem/8807070>.

Douglas Gregor 5cde386e5e When mapping from a function parameter pack to the set of function 
parameters it expanded to, map exactly the number of function
parameters that were expanded rather than just running to the end of
the instantiated parameter list. This finishes the implementation of
the last sentence of C++0x [temp.deduct.call]p1.

Douglas Gregor 0dd423ef33 Implement the last bullet of [temp.deduct.type]p5 and part of the last 
sentence of [temp.deduct.call]p1, both of which concern the
non-deducibility of parameter packs not at the end of a
parameter-type-list. The latter isn't fully implemented yet; see the
new FIXME.

Chandler Carruth b1e7f557b7 Teach constant folding to perform conversions from constant floating 
point values to their integer representation through the SSE intrinsic
calls. This is the last part of a README.txt entry for which I have real

Douglas Gregor 8008ba75a5 Add testing for unexpanded parameter packs in all of the C++ 
expression kinds. This is (indirectly) a test verifying that the
recursive AST visitor is visiting the children of these expression
nodes.

Rafael Espindola b7f60e3474 Add unnamed_addr when creating artificial string globals. For example, in 
static const char foo[] = "foo";
static const char *bar = "bar";

the global created to hold "bar" will have it, but foo will not.

Dale Johannesen d2b48119b0 Fix PR 8916 (qv for analysis), at least the immediate problem. 
There's an inherent tension in DAGCombine between assuming
that things will be put in canonical form, and the Depth
mechanism that disables transformations when recursion gets
too deep.  It would not surprise me if there's a lot of little
bugs like this one waiting to be discovered.  The mechanism
seems fragile and I'd suggest looking at it from a design viewpoint.

Douglas Gregor 48d2411597 Implement more of C++0x [temp.arg.explicit]p9, allowing extension of 
pack expansions in template argument lists and function parameter
lists. The implementation of this paragraph should be complete
*except* for cases where we're substituting into one of the unexpanded
packs in a pack expansion; that's a general issue I haven't solved yet.
