Greg Clayton 1c870d6e9f One more fix to:
bool SectionLoadList::ResolveLoadAddress (addr_t load_addr, Address &so_addr) const;

Where if the address is in the last map entry, we need to look it up correctly.
My previous fix was incorrect where it looked in the first if there were
no addresses in the map that were > load_addr. Now we correctly look in the
last entry if our std::map::lower_bound search returns the end of the 
collection.

Greg Clayton c5e9a7dc2b Fixed an issue where addresses would not get resolved for the last
loaded section in the section load list.

Greg Clayton 6d0934519d Added a quicker lookup in the SectionLoadList when looking things up by
section by using a DenseMap.

Fixed some logging calls to get the log shared pointer.

Jason Molenda f830e481c2 RegisterContextLLDB.cpp (InitializeNonZerothFrame): If we get a
0 mid-stack, stop backtracing.

SectionLoadList.cpp (ResolveLoadAddress): Don't assert on an
out-of-range address, just return an invalid Address object.
The unwinder may be passing in invalid addresses on the final
stack frame and the assert is a problem.

Greg Clayton 8b2fe6dcbd Modified LLDB expressions to not have to JIT and run code just to see variable
values or persistent expression variables. Now if an expression consists of
a value that is a child of a variable, or of a persistent variable only, we
will create a value object for it and make a ValueObjectConstResult from it to
freeze the value (for program variables only, not persistent variables) and
avoid running JITed code. For everything else we still parse up and JIT code
and run it in the inferior. 

There was also a lot of clean up in the expression code. I made the 
ClangExpressionVariables be stored in collections of shared pointers instead
of in collections of objects. This will help stop a lot of copy constructors on
these large objects and also cleans up the code considerably. The persistent
clang expression variables were moved over to the Target to ensure they persist
across process executions.

Added the ability for lldb_private::Target objects to evaluate expressions.
We want to evaluate expressions at the target level in case we aren't running
yet, or we have just completed running. We still want to be able to access the
persistent expression variables between runs, and also evaluate constant 
expressions. 

Added extra logging to the dynamic loader plug-in for MacOSX. ModuleList objects
can now dump their contents with the UUID, arch and full paths being logged with
appropriate prefix values.

Thread hardened the Communication class a bit by making the connection auto_ptr
member into a shared pointer member and then making a local copy of the shared
pointer in each method that uses it to make sure another thread can't nuke the
connection object while it is being used by another thread.

Added a new file to the lldb/test/load_unload test that causes the test a.out file
to link to the libd.dylib file all the time. This will allow us to test using
the DYLD_LIBRARY_PATH environment variable after moving libd.dylib somewhere else.

Greg Clayton 10177aa05e Added the ability to dump sections to a certain depth (for when sections
have children sections).

Modified SectionLoadList to do it's own multi-threaded protected on its map.
The ThreadSafeSTLMap class was difficult to deal with and wasn't providing
much utility, it was only getting in the way.

Make sure when the communication read thread is about to exit, it clears the
thread in the main class.

Fixed the ModuleList to correctly ignore architectures and UUIDs if they aren't
valid when searching for a matching module. If we specified a file with no arch,
and then modified the file and loaded it again, it would not match on subsequent
searches if the arch was invalid since it would compare an invalid architecture
to the one that was found or selected within the shared library or executable.
This was causing stale modules to stay around in the global module list when they
should have been removed.

Removed deprecated functions from the DynamicLoaderMacOSXDYLD class.

Modified "ProcessGDBRemote::IsAlive" to check if we are connected to a gdb
server and also make sure our process hasn't exited.

Greg Clayton 2d4edfbc6a Modified all logging calls to hand out shared pointers to make sure we
don't crash if we disable logging when some code already has a copy of the
logger. Prior to this fix, logs were handed out as pointers and if they were
held onto while a log got disabled, then it could cause a crash. Now all logs
are handed out as shared pointers so this problem shouldn't happen anymore.
We are also using our new shared pointers that put the shared pointer count
and the object into the same allocation for a tad better performance.

Jim Ingham 3cbb931504 Don't need both LIBLLDB_LOG_DYNAMIC_LOADER and LIBLLDB_LOG_SHLIB. Go with the former.

Add missing files that I forgot to checkin.
