Added the ability to extract a ModuleSpecList (a new class) from an ObjectFile. This is designed to be used when you have an object file that contains one or more architectures (MacOSX universal (fat) files) and/or one or more objects (BSD archive (.a files)).

There is a new static ObjectFile function you can call:

size_t
ObjectFile::GetModuleSpecifications (const FileSpec &file,
                                     lldb::offset_t file_offset,
                                     ModuleSpecList &specs)

This will fill in "specs" which the details of all the module specs (file + arch + UUID (if there is one) + object name (for BSD archive objects eventually) + file offset to the object in question).

This helps us when a user specifies a file that contains a single architecture, and also helps us when we are given a debug symbol file (like a dSYM file on MacOSX) that contains one or more architectures and we need to be able to match it up to an existing Module that has no debug info.

The user was trying to obtain the address-of an std::vector and the experience was more painful than necessary because data formatters were kicking in for vector* objects
We got this right for libc++ - we should get it right for libstdc++ too

Fixed LLDB to be able to correctly parse template parameters that have no name and no type. This can be triggered by the following LLVM/Clang code:

template <typename T, typename = void>
class SmallVectorTemplateCommon : public SmallVectorBase {

The “typename = void” was emitting DWARF with an empty DW_AT_name and no DW_AT_type. We now correctly infer that no DW_AT_type means “void” and that an empty name is ok.

This means you can now call functions on things that inherit from SmallVectorTemplateCommon.

Be sure to print out the fully mangled name when we are unable to find a function to call so we can easily look for this symbol if needed.

Patch by Yacine Belkadi!

When __GLIBC__ is defined, optind gets initialized to 0. So for the first parsed
option, parse_start is 0, too. If this option has no argument (Like "--continue"
of "process attach"), then the position stored is 0, instead of 1. This prevents
the completion later on in Options::HandleOptionCompletion() because the opt_pos
doesn't match the cursor_index.

Fix that by getting the option's position from the value of optind, as it's done
for the other types of options.

Re-enable test_process_attach_dash_dash_con() on Linux.

No regressions detected on Mac OS X (in TestCompletion.py)
