Jason Molenda 880988af09 ProcessMachCore scans through the core file pages looking for a
user process dyld binary and/or a mach kernel binary image.  By
default, it prefers the kernel if it finds both.

But if it finds two kernel binary images (which can happen when
random things are mapped into memory), it may pick the wrong
kernel image.  

DynamicLoaderDarwinKernel has heuristics to find a kernel in memory;
once we've established that there is a kernel binary in memory,
call over to that class to see if it can find a kernel address via
its search methods.  If it does, use that.

Some minor cleanups to DynamicLoaderDarwinKernel while I was at it.

Enrico Granata 0a66e2f135 Fix an issue where certain CommandObjects (or Options thereof) were being created once, bound to a specific CommandInterpreter (and hence a specific Debugger), and then cached for reuse across different Debugger instances
Obviously, if the original Debugger goes away, those commands are holding on to now stale memory, which has the potential to cause crashes

Siva Chandra 375882dddb Use an artifical namespace so that member vars do not hide local vars.
Summary:
While evaluating expressions when stopped in a class method, there was a
problem of member variables hiding local variables. This was happening
because, in the context of a method, clang already knew about member
variables with their name and assumed that they were the only variables
with those names in scope. Consequently, clang never checks with LLDB
about the possibility of local variables with the same name and goes
wrong. This change addresses the problem by using an artificial
namespace "$__lldb_local_vars". All local variables in scope are
declared in the "$__lldb_expr" method as follows:

    using $__lldb_local_vars::<local var 1>;
    using $__lldb_local_vars::<local var 2>;
    ...

This hides the member variables with the same name and forces clang to
enquire about the variables which it thinks are declared in
$__lldb_local_vars. When LLDB notices that clang is enquiring about
variables in $__lldb_local_vars, it looks up local vars and conveys
their information if found. This way, member variables do not hide local
variables, leading to correct evaluation of expressions.

A point to keep in mind is that the above solution does not solve the
problem for one specific case:

    namespace N
    {
        int a;
    }

    class A
    {
    public:
        void Method();
        int a;
    };

    void
    A::Method()
    {
        using N::a;
        ...

        // Since the above solution only touches locals, it does not
        // force clang to enquire about "a" coming from namespace N.
    }

This patch adds a custom expression options member class to LanguageOptions, and modifies the clang expression evaluator to check the current runtime for those options. If those options are available on the runtime, they are passed to the clang compiler.

RangeMap.h also contained a class called AddressDataArray what have very
little added functionality over an std::vector and used only by
ObjectFileMacO The CL moves the class to ObjectFileMachO.cpp as it isn't
belongs into RangeMap.h and shouldn't be used in new places anyway

Tamas Berghammer 8e18fe6e54 Fix single stepping over the IT instruction
The ARM instruction emulator had 2 bugs related to the handling of the
IT instruction causing an error in single stepping:
* We haven't initialized the IT mask from the CPSR so if the last
  instruction of the IT block is a branch and the condition is false
  then the emulator evaluated the branch what resulted in an incorrect
  pc for the next instruction.
* The ITSTATE was advanced before the execution of each instruction. As
  a result the emulator was using the condition of following instruction
  in every case. The ITSTATE should be edvanced after the execution of
  an instruction except after an IT instruction.

Pavel Labath 061140c680 Remove Timer::Initialize routine
Summary:
I've run into an issue when running unit tests, where the underlying problem turned out to be
that we were creating Timer objects (through several layers of indirection) without calling
Timer::Initialize. Since Timer's thread-local storage was not properly initialized, we were
overwriting gtest's own thread-local storage, causing test failures.

Instead of requiring that every test calls Timer::Initialize(), I remove the function altogether:
The thread-local storage can be initialized on-demand, and the g_file variable initialized to
stdout and never changed, so I have simply removed it.

 - Summary:
      When a trace event is reported, we need to check
      whether the trace event lands at a breakpoint site.

      If it lands at a breakpoint site then set the thread's
      StopInfo with the reason 'breakpoint'. Else, set the reason
      to be 'Trace'.

Greg Clayton 17499dde46 A while back in revison 244716 we added support for getting the host OS version info from debugserver. We added keys to "qHostInfo" that were "osmajor", "osminor" and "ospatch", but no one ever parsed those, so I am removing them from debugserver. We accidentally also added a "version" key to qHostInfo instead of "os_version". So now we need to support both "version" and "os_version" in qHostInfo since we have debugserver binaries out in the wild that support this old packet type. I have updated debugserver ot use the correct "os_version" for future compatability or correctness.
