Fixed an LLVM/Clang assertion that would happen for C++ and ObjC methods if the DWARF doesn't specify the accessibility for the method. Currently gcc 4.2 and clang++ do not set the accessibility correctly on methods. We currently shouldn't default to private since public methods don't have the accessibility specified. 

Bottom line: we currently default to public for both C++ and ObjC if the accessibility isn't set.

MCStreamer to emit into instead of an MCInst to fill in.  This allows the

problems with phi-nodes in blocks that have hard and not virtual registers.

adding methods to C++ and objective C classes. In order to make methods, we
need the function prototype which means we need the arguments. Parsing these
could cause a circular reference that caused an  assertion.

Added a new typedef for the clang opaque types which are just void pointers:
lldb::clang_type_t. This appears in lldb-types.h.

This was fixed by enabling struct, union, class, and enum types to only get
a forward declaration when we make the clang opaque qual type for these
types. When they need to actually be resolved, lldb_private::Type will call
a new function in the SymbolFile protocol to resolve a clang type when it is
not fully defined (clang::TagDecl::getDefinition() returns NULL). This allows
us to be a lot more lazy when parsing clang types and keeps down the amount
of data that gets parsed into the ASTContext for each module. 

Getting the clang type from a "lldb_private::Type" object now takes a boolean
that indicates if a forward declaration is ok:

    clang_type_t lldb_private::Type::GetClangType (bool forward_decl_is_ok);
    
So function prototypes that define parameters that are "const T&" can now just
parse the forward declaration for type 'T' and we avoid circular references in
the type system.

completely into CXXRecordDecl, by adding a new completeDefinition()
function. This required a little reshuffling of the final-overrider
checking code, since the "abstract" calculation in the presence of
abstract base classes needs to occur in
CXXRecordDecl::completeDefinition() but we don't want to compute final
overriders more than one in the common case.

delete the MDNode that changed, rather than the other MDNode.
This is less work, because it doesn't require the changed node
to be re-inserted into the uniquing map and it doesn't require
the is-function-local flag to be recomputed. Also, it avoids
trouble when the existing node is part of a complicated
data structure.

cost modeling for if-conversion.  Now if only we had a way to estimate the misprediction probability.

Adjsut CodeGen/ARM/ifcvt10.ll.  The pipeline on Cortex-A8 is long enough that it is still profitable
to predicate an ldm, but the shorter pipeline on Cortex-A9 makes it unprofitable.

 - the guard variable for the static result

TestFloatTypes.py, which exercise 'frame variable' on the various basic types.

Right now, they don't employ the self.expect() facility to compare against the
golden output.  They just invoke the self.runCmd() method to run the 'expr'
command.  Decorated the two classes with @unittest2.skip decorators for the time
being.

This reinstates r114924, with one crucial bug fix: we were ignoring
the implicit fields created by anonymous structs/unions when updating
the bits in CXXRecordDecl, which means that a class/struct containing
only an anonymous class/struct would be considered "empty". Hilarity
follows.
