actually pre-define, so instead of expanding the macro location, refer to the
instantiation location and name it using the macro loc.

ELF object files do not implicitly have a symbol named "start" as an entry
point.  For example, on Linux it is often named "_start", but can be trivially
set to any symbol by passing an --entry argument to the linker.

Use the ELF header to determine the entry point and resolve the associated
section based on that address.

Also, update the linux dynamic loader to call GetEntryPointAddress instead of
GetEntryPoint.

testcases accordingly. Some are currently xfailed and will be filed
as bugs to be fixed or understood.

Performance results:

roughly neutral on SPEC
some micro benchmarks in the llvm suite are up between 100 and 150%, only
a pair of regressions that are due to be investigated

john-the-ripper saw:
10% improvement in traditional DES
8% improvement in BSDI DES
59% improvement in FreeBSD MD5
67% improvement in OpenBSD Blowfish
14% improvement in LM DES

Small compile time impact.

I didn't notice there was already an ObjectFile::GetEntryPoint.  Move that over to GetEntryPointAddress 'cause that's more consistent with other functions in ObjectFile, do the mutatis mutandi and also in the ELF case I return a section offset address rather than a bare load address.

This change uses the MaxReorderWindow for both height and depth, which
tends to limit the negative effects of high register pressure.

Add a method "GetEntryPoint" to the ObjectFile class, and implement it on MachO & ELF - though the ELF implementation is probably a little weak.  Then use this method in place of directly looking for "start" in the ThreadPlanCallFunction constructor to find the stopping point for our function evaluation.

Add thread state initialization to the thread where the interactive
interpreter is run (which is separate from the thread where
Py_Initialize is called, where this normally gets set up).

clobber with the 'y' constraint. Otherwise, we get the wrong return type and an
assert, because it created a '<1 x i64>' vector type instead of the x86_mmx
type.

Currently it has only test cases for SBThread.GetStopDescription() API.

Also modified lldb.swig to add typemap for (char *dst, size_t dst_len)
which occurs for SBThread::GetStopDescription() C++ API.  For Python
scripting:

    # Due to the typemap magic (see lldb.swig), we pass in an (int)length to GetStopDescription
    # and expect to get a Python string as the result object!
    # The 100 is just an arbitrary number specifying the buffer size.
    stop_description = thread.GetStopDescription(100)
