ability to dump more information about modules in "target modules list". We
can now dump the shared pointer reference count for modules, the pointer to
the module itself (in case performance tools can help track down who has
references to said pointer), and the modification time.

Added "target delete [target-idx ...]" to be able to delete targets when they
are no longer needed. This will help track down memory usage issues and help 
to resolve when module ref counts keep getting incremented. If the command gets
no arguments, the currently selected target will be deleted. If any arguments 
are given, they must all be valid target indexes (use the "target list" 
command to get the current target indexes).

Took care of a bunch of "no newline at end of file" warnings.

TimeValue objects can now dump their time to a lldb_private::Stream object.

Modified the "target modules list --global" command to not error out if there
are no targets since it doesn't require a target.

Fixed an issue in the MacOSX DYLD dynamic loader plug-in where if a shared 
library was updated on disk, we would keep using the older one, even if it was
updated.

Don't allow the ModuleList::GetSharedModule(...) to return an empty module.
Previously we could specify a valid path on disc to a module, and specify an
architecture that wasn't contained in that module and get a shared pointer to
a module that wouldn't be able to return an object file or a symbol file. We
now make sure an object file can be extracted prior to adding the shared pointer
to the module to get added to the shared list.

into the mainline LLDB codebase.  MCJIT introduces
API improvements and better architectural support.

This commit adds a new subsystem, the
ProcessDataAllocator, which is responsible for
performing static data allocations on behalf of the
IR transformer.  MCJIT currently does not support
the relocations required to store the constant pool
in the same allocation as the function body, so we
allocate a heap region separately and redirect
static data references from the expression to that
heap region in a new IR modification pass.

This patch also fixes bugs in the IR
transformations that were exposed by the transition
to the MCJIT.  Finally, the patch also pulls in a
more recent revision of LLVM so that the MCJIT is
available for use.
