when deserialized, fixing random crashes in libclang.

Also simplifies how OpaqueValueExprs are [de]serialized.
The reader/writer automatically retains pointer equality of sub-statements (when a
statement node is referenced in multiple nodes), so no need to manually handle it.

for all our external AST sources that lets us associate
arbitrary flags with the types we put into the AST
contexts.  Also added an API on ClangASTContext that
allows access to these flags given only an ASTContext
and a type.

Because we don't have access to RTTI, and because at
some point in the future we might encounter external
AST sources that we didn't make (so they don't subclass
ClangExternalASTSourceCommon) I added a magic number
that we check before doing anything else, so that we
can catch that problem as soon as it appears.

matter since the old JIT is going away. Add tsan annotations to ignore the
race.

object file can correctly make these symbols which will abstract us from the
file format and ABI and we can then ask for the objective C class symbol for
a class and find out which object file it was defined in.

the function it is being asked to step through, so that even if we get the trampoline
target wrong (for instance) we will still not lose control.

The other fix here is to tighten up the handling of the case where the current plan
doesn't explain the stop, but a plan above us does.  In that case, if the plan that
does explain the stop says it is done, we need to clean up the plans below it and 
continue on with our processing.

Module files representing actual modules don't need to know the set of modules they import, since that information isn't actually used. Drop it from the AST file

"main" files that import modules. When loading any of these kinds of
AST files, we make the modules that were imported visible into the
translation unit that loaded the PCH file or preamble.

Fixed an issue where if we have the DWARF equivalent of:

struct foo;

class foo { ... };

Or vice versa, we wouldn't be able to find the complete type. Since many
compilers allow forward declarations to have struct and definitions to have
class, we need to be able to deal with both cases. This commit fixes this in
the DWARF parser.

change, now you need a TargetOptions object to create a TargetMachine. Clang
patch to follow.

One small functionality change in PTX. PTX had commented out the machine
verifier parts in their copy of printAndVerify. That now calls the version in
LLVMTargetMachine. Users of PTX who need verification disabled should rely on
not passing the command-line flag to enable it.
