Adds assembly parsing support for the module summary index (follow on
to r333335 which added the assembly writing support).

I added support to llvm-as to invoke the index parsing, so that it can
create either a bitcode file with a Module and a per-module index, or
a combined index without a Module.

I will send follow on patches soon to do the following:

- add support to tools such as llvm-lto2 to parse the per-module indexes

from assembly instead of bitcode when testing the thin link.

- verification support.

I wanted to get the guts of the parsing out for review now though.
