iteration.
  
  This on step toward non-iterative GVN. My local hack suggests that getting rid
of iteration will speedup GVN by 30%+ on a medium sized input (2k LOC, C++).
I cannot explain why not 2x or more at this moment.

getInvertedPredicatedOpcode() functions instead of switch cases.

The compact unwind registers were defined in two different
places. It's better just to place them in the function that uses them
and specify that this is a 64-bit or 32-bit machine.

This patch fixes PR15601.
- Added check for whether the loop variable and the initializer have the same
type.
- Added tests.

Fix the return type of the complex creal functions. Patch by YunZhong Gao, modified to use _Static_assert and to check __STDC_HOSTED__ by me.

Previously we only checked if the LR required saving if the frame size was
non zero. However because the caller reserves 1 word for the callee to use
that doesn't count towards our frame size it is possible for the LR to need
saving and for the frame size to be 0.

We didn't hit when the LR needed saving because of a function calls because
the 1 word of stack we must allocate for our callee means the frame size
is always non zero in this case. However we can hit this case if the LR is
clobbered in inline asm.

That's obviously wrong. Conservatively restrict it to the sign bit, which
matches the original intention of this analysis. Fixes PR15940.

object x, x's subobjects can be constructed by constexpr constructor even if

namespace lldb_private {
    class Thread
    {
        virtual lldb::StopInfoSP
        GetPrivateStopReason() = 0;
    };
}

To not be virtual. The lldb_private::Thread now handles the correct caching and will call a new pure virtual function:

namespace lldb_private {
    class Thread
    {
        virtual bool
        CalculateStopInfo() = 0;
    }
}

This function must be overridden by thead lldb_private::Thread subclass and the only thing it needs to do is to set the Thread::StopInfo() with the current stop reason and return true, or return false if there is no stop reason. The  lldb_private::Thread class will take care of calling this function only when it is required. This allows lldb_private::Thread subclasses to be a bit simpler and not all need to duplicate the cache and invalidation settings.

Also renamed:

lldb::StopInfoSP
lldb_private::Thread::GetPrivateStopReason();

To:

lldb::StopInfoSP
lldb_private::Thread::GetPrivateStopInfo();

Also cleaned up a case where the ThreadPlanStepOverBreakpoint might not re-set its breakpoint if the thread disappears (which was happening due to a bug when using the OperatingSystem plug-ins with memory threads and real threads).

to the DeclContext.  This fulfils the contract that
we make with Clang by returning ELR_AlreadyLoaded.

This is a little aggressive in that it does not allow
the ASTImporter to import the child decls with any
lexical parent other than the Decl that reported them
as children.

Changing the std::map test case to use source breakpoints instead of relying on the nexting always "getting it right" to stop at the locations of interest

clang would omit 'C' for 'copy' properties and '&' for 'retain' properties if
the property was also 'readonly'. Fix this, which makes clang match gcc4.2's
behavior.
