    bool ValueObject::GetIsConstant() const;
    void ValueObject::SetIsConstant();

This will stop anything from being re-evaluated within the value object so
that constant result value objects can maintain their frozen values without
anything being updated or changed within the value object.

Made it so the ValueObjectConstResult can be constructed with an 
lldb_private::Error object to allow for expression results to have errors.

Since ValueObject objects contain error objects, I changed the expression
evaluation in ClangUserExpression from 

    static Error
    ClangUserExpression::Evaluate (ExecutionContext &exe_ctx, 
                                  const char *expr_cstr, 
                                  lldb::ValueObjectSP &result_valobj_sp);

to:

    static lldb::ValueObjectSP
    Evaluate (ExecutionContext &exe_ctx, const char *expr_cstr);
    
Even though expression parsing is borked right now (pending fixes coming from
Sean Callanan), I filled in the implementation for:
    
    SBValue SBFrame::EvaluateExpression (const char *expr);
    
Modified all expression code to deal with the above changes.

for the same destination, then we must potentially rewrite the initial branch
of every fixup.  Without this patch, a short-circuit check meant to prevent
a switch case from being redundantly added was preventing later fixups from
being processed.  Fixes PR8175 (again).

results. The clang opaque type for the expression result will be added to the
Target's ASTContext, and the bytes will be stored in a DataBuffer inside
the new object. The class is named: ValueObjectConstResult

Now after an expression is evaluated, we can get a ValueObjectSP back that
contains a ValueObjectConstResult object.

Relocated the value object dumping code into a static function within
the ValueObject class instead of being in the CommandObjectFrame.cpp file
which is what contained the code to dump variables ("frame variables").

Make sure it restores local variable N1, which corresponds to the condition operand if it fails to match.

This apparently breaks TCE but since that backend isn't in the tree I don't have a test for it.

1) Changed ValidateDwarfFileNumber() to isValidDwarfFileNumber() to be better
   named.  Since it is just a predicate and isn't actually changing any state.

2) Added a missing return in the comments for setCurrentDwarfLoc() in 
   include/llvm/MC/MCContext.h for fix formatting.

3) Changed clearDwarfLocSeen() to ClearDwarfLocSeen() since it does change
   state.

4) Simplified the last test in isValidDwarfFileNumber() to just a one line
   boolean test of MCDwarfFiles[FileNumber] != 0 for the final return statement.

Still working on the basic design of <atomic>.  I'm working towards a system by which the compiler only needs to define the strongest intrinsics it can.  Weaker atomics in the library automatically try stronger and stronger variants, picking the weakest compiler intrinsic available.  If no compiler intrinsics are available for a given operation, the library locks a mutex and does the job.  Better documentation to follow...
