Add a FIXME to the test while I track down the real problem.

The problem is that the value of 'this' in a C++ member function call
should always be a region (or NULL). However, if the object is an rvalue,
it has no associated region (only a conjured symbol or LazyCompoundVal).
For now, we handle this in two ways:

1) Actually respect MaterializeTemporaryExpr. Before, it was relying on
   CXXConstructExpr to create temporary regions for all struct values.
   Now it just does the right thing: if the value is not in a temporary
   region, create one.

2) Have CallEvent recognize the case where its 'this' pointer is a
   non-region, and just return UnknownVal to keep from confusing clients.

The long-term problem is being tracked internally in <rdar://problem/12137950>,
but this makes many test cases pass.

No intended functionality change.

llvm-svn: 163219

This turned out to have many implications, but what eventually seemed to
make it unworkable was the fact that we can get struct values (as
LazyCompoundVals) from other places besides return-by-value function calls;
that is, we weren't actually able to "treat all struct values as regions"
consistently across the entire analyzer core.

Hopefully we'll be able to come up with an alternate solution soon.

This reverts r163066 / 02df4f0aef142f00d4637cd851e54da2a123ca8e.

Make sure to return a pointer into the target memory, not the local memory.
Often they are the same, but we can't assume that.

llvm-svn: 163217

Simulate a remote target address space by allocating a seperate chunk of
memory for the target and re-mapping section addresses to that prior to
execution. Later we'll want to have a truly remote process, but for now
this gets us closer to being able to test the remote target
functionality outside LLDB.

It relies on clear() being fast and the cache rarely has more than 1 or 2
elements, so give it an inline capacity and always shrink it back down in case
it grows. DenseMap will grow to 64 buckets which makes clear() a lot slower.

Due to DynTypedNode the basic dynamically typed matcher interface can now be simplified.

Also switches the traversal interfaces to use DynTypedNode;
this is in preperation for the hasAncestor implementation, and
also allows us to need fewer changes when we want to add new
nodes to traverse, thus making the code a little more decoupled.

Main design concerns: I went back towards the original design
of getNodeAs to return a pointer, and switched DynTypedNode::get
to always return a pointer (in case of value types like QualType
the pointer points into the storage of DynTypedNode, thus allowing
us to treat all the nodes the same from the point of view of a
user of the DynTypedNodes.

Adding the QualType implementation for DynTypedNode was needed
for the recursive traversal interface changes.

Fixed the DAG combiner to better handle the folding of AND nodes for vector types. The previous code was making the assumption that the length of the bitmask returned by isConstantSplat was equal to the size of the vector type. Now we first make sure that the splat value has at least the length of the vector lane type, then we only use as many fields as we have available in the splat value.
