which will in the future allow expressions to be
compiled as C, C++, and Objective-C instead of the
current default Objective-C++.  This feature requires
some additional support from Clang -- specifically, it
requires reference types in the parser regardless of
language -- so it is not yet exposed to the user.

Fix the test suite failure.  The particular line in the test case was there since the initial version
dated 2010-21-15.  The test started failure recently probably due to work done on the command parsing.
Anyway, the specific test sequence is invalid and is fixed now.

 a) adds a new --synchronicity (-s) setting for "command script add" that allows the user to decide if scripted commands should run synchronously or asynchronously (which can make a difference in how events are handled)
 b) clears up several error messages
 c) adds a new --allow-reload (-r) setting for "command script import" that allows the user to reload a module even if it has already been imported before
 d) allows filename completion for "command script import" (much like what happens for "target create")
 e) prevents "command script add" from replacing built-in commands with scripted commands
 f) changes AddUserCommand() to take an std::string instead of a const char* (for performance reasons)
plus, it fixes an issue in "type summary add" command handling which caused several test suite errors

Joel Dillon that fixed 64 debugging for Linux.

I also added a patch to fix up the ProcessLinux::DoLaunch() to be up to date.
I wasn't able to verify it compiles, but it should b really close.

C++ vtables, fixing a record layout problem in the
expression parser.

Also fixed various problems with the generation 
and unpacking of llvm.zip given our new better
handling of multiple architectures in the LLVM
build.

(And added a log message that will hopefully catch
record layout problems in the future.)

we often nuke our "build" folder so we can do clean builds. This way if you
are building your own LLVM you won't have to rebuild LLVM when you do remove
your build folder. The new location for the LLVM build is:

- If you download and build the sources in the Xcode project, x86_64 builds
  by default using the "llvm.zip" checkpointed LLVM.
- If you delete the "lldb/llvm.zip" and the "lldb/llvm" folder, and build the
  Xcode project will download the right LLVM sources and build them from 
  scratch
- If you have a "lldb/llvm" folder already that contains a "lldb/llvm/lib"
  directory, we will use the sources you have placed in the LLDB directory.
  
Python can now be disabled for platforms that don't support it. 

Changed the way the libllvmclang.a files get used. They now all get built into
arch specific directories and never get merged into universal binaries as this
was causing issues where you would have to go and delete the file if you wanted
to build an extra architecture slice.

target is stopped in a C++ or Objective-C method
but the "self" pointer's valid range actually
doesn't cover the current location.  Before, that
was confusing Clang to the point where it crashed;
now, we sanity-check and fall back to pretending
we're in a C function if "self" or "this" isn't
available.

allows us to set __attribute__ ((used)) on expressions
that masquerade as methods.  When we are stopped in
classes in anonymous namespaces, this fix (and enabling
__attribute__ ((used)) on the method) will allow
expressions to run.

Fixed an issue where the DWARF might mention that a class has a constructor
(default, copy or move), destructor, or an assignment operator (copy or move)
and it might not have an actual implementation in your code. Then you try and
use this struct or class in an expression and the JIT would ask for the 
address of these methods that were in the declaration, yet there are none.
We now "do the right thing" for trivial ctors, dtors and assignment operators
by telling the methods that they are are defaulted and trivial, and clang will
then just do all of the work with builtins!

llvm-svn: 143528

generated special member functions (constructors,
destructors, etc.) for classes that don't really have
them.  We needed to mark these as artificial to reflect
the debug information; this bug does that for
constructors and destructors.

The "etc." case (certain assignment operators, mostly)
remains to be fixed.

correctly, and added a testcase to check that it works.

The main problem here is that Objective-C class method
selectors are external references stored in a special
data structure in the LLVM IR module for an expression.
I just had to extract them and ensure that the real
class object locations were properly resolved.

method as __attribute__ ((used)) when adding it to a
class.  This functionality is useful when stopped in
anonymous namespaces: expressions attached to classes
in anonymous namespaces are typically elided by Clang's
CodeGen because they have no namespaces are intended
not to be externally visible.  __attribute__ ((used))
forces CodeGen to emit the function.

Right now, __attribute__ ((used)) causes the JIT not to
emit the function, so we're not enabling it until we
fix that.

RegisterContextLLDBs it contains.

Previously RegisterContextLLDB objects had a pointer to their "next"
frame down the stack.  e.g. stack starts at frame 0; frame 3 has a
pointer to frame 2.  This is used to retreive callee saved register
values.  When debugging an inferior that has blown out its own stack,
however, this could result in lldb blowing out its own stack while
recursing down to retrieve register values.

RegisterContextLLDB no longer has a pointer to its next frame; it 
has a reference to the UnwindLLDB which contains it.  When it needs
to retrieve a reg value, it asks the UnwindLLDB for that reg value
and UnwindLLDB iterates through the frames until it finds a location.

"object borked"...  Also made the error when the checker fails reflect this fact rather than
report a crash at 0x0.

Also a little cleanup:
- StopInfoMachException had a redundant copy of the description string.
- ThreadPlanCallFunction had a redundant copy of the thread, and had a 
copy of the process that it didn't really need.
