When looking up the 'self' decl in block captures, make sure to find the actual
self declaration even when the block captures a local variable named 'self'.

clang converts C++ lambdas to blocks with an implicit user-defined conversion
operator method on the lambda record. This method returns a block that captures a copy
of the lambda. To inline a lambda-converted block, the analyzer now calls the lambda
records's call operator method on the lambda captured by the block.

Don't warn about addresses of stack-allocated blocks escaping if the block
region was cast with CK_CopyAndAutoreleaseBlockObject. These casts, which
are introduced in the implicit conversion operator for lambda-to-block
conversions, cause the block to be copied to the heap -- so the warning is
spurious.

This prevents spurious dead store warnings when a C++ lambda is casted to a block.
I've also added several tests documenting our still-incomplete support for lambda-to-block
casts.

When calling a ObjC method on super from inside a C++ lambda, look at the
captures to find "self". This mirrors how the analyzer handles calling super in
an ObjC block and fixes an assertion failure.
