A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error.
This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness.

LLDB is crashing when logging is enabled from lldb-perf-clang. This has to do with the global destructor chain as the process and its threads are being torn down.
All logging channels now make one and only one instance that is kept in a global pointer which is never freed. This guarantees that logging can correctly continue as the process tears itself down.

of problems with Objective-C object completion. To go
along with the LLVM/Clang-side fixes, we have a variety
of Objective-C improvements.
Fixes include:
- It is now possible to run expressions when stopped in
an Objective-C class method and have "self" act just
like "self" would act in the class method itself (i.e.,
[self classMethod] works without casting the return
type if debug info is present). To accomplish this,
the expression masquerades as a class method added by
a category.
- Objective-C objects can now provide methods and
properties and methods to Clang on demand (i.e., the
ASTImporter sets hasExternalVisibleDecls on Objective-C
interface objects).
- Objective-C built-in types, which had long been a bone
of contention (should we be using "id"? "id*"?), are
now fetched correctly using accessor functions on
ClangASTContext. We inhibit searches for them in the
debug information.
There are also a variety of logging fixes, and I made two
changes to the test suite:
- Enabled a test case for Objective-C properties in the
current translation unit.
- Added a test case for calling Objective-C class methods
when stopped in a class method.

std::string and modified all places that used the std::string it returned
to use the "const char *".
Also modified the expression parser to not crash when a function type fails
to copy into the expression AST context.

we never used) with a much simpler class that wraps
the relevant dump functions in Clang. This class also
knows to disable external lookups on DeclContexts
being dumped so it should be safe to print incomplete
Decls.

This involved minor changes to the way we report Objective-C
methods, as well as cosmetic changes and added parameters
for a variety of Clang APIs.

completes the support in the LLDB expression parser
for incomplete types. Clang now imports types
lazily, and we complete those types as necessary.
Changes include:
- ClangASTSource now supports three APIs which it
passes to ClangExpressionDeclMap. CompleteType
completes a TagDecl or an ObjCInterfaceDecl when
needed; FindExternalVisibleDecls finds named
entities that are visible in the expression's
scope; and FindExternalLexicalDecls performs a
(potentially restricted) search for entities
inside a lexical scope like a namespace. These
changes mean that entities in namespaces should
work normally.
- The SymbolFileDWARF code for searching a context
for a specific name is now more general, and can
search arbitrary contexts.
- We are continuing to adapt our calls into LLVM
from interfaces that take start and end iterators
when accepting multiple items to interfaces that
use ArrayRef.
- I have cleaned up some code, especially our use
of namespaces.
This change is neutral for our testsuite and greatly
improves correctness for large programs (like Clang)
with complicated type systems. It should also lay
the groundwork for improving the expression parser's
performance as we are lazier and lazier about
providing type information.

diagnostics of Clang AST classes for the purpose of
debugging the types LLDB produces for DWARF objects.
The ASTDumper is currently only used in log output
if you enable verbose mode in the expression log:
log enable -v lldb expr
Its output then appears in the log for external
variables used by the expr command.
