This moves the "gdbarch" field from the objfile into the BFD.
This field's value is derived from the BFD and is immutable over the
lifetime of the BFD. This makes it a reasonable candidate for pushing
into the per-BFD object.
This is part of the long-term objfile splitting project. In the long
run I think this patch will make it simpler to moves types from the
objfile to the per-BFD object; but the patch makes sense as a minor
cleanup by itself.

With "dwz -m", "main" appears in both the PU and the importing CU when
running anon-struct.exp. However, the PU does not have a file name.
So, find_main_filename returns the empty string, making
deduce_language_from_filename return language_unknown.
This patch fixes this problem by changing gdb to use the ordinary
symbol-lookup functions to find "main"'s symbol. Then, it examines the
symbol's language.
I think this is cleaner than the current approach. For one thing it
avoids trying to guess the language based on the source file name,
instead deferring to the presumably more reliable debuginfo.
Another possible fix would have been to change how the file name is
found via the "qf" methods. However, I think the approach given is
preferable for the reason outlined above.
This required a minor test suite change, as now a symtab is expanded
during the search for "main".
Built and regtested (both ways) on x86-64 Fedora 18.
* symfile.c (set_initial_language): Look up "main" symbol
and use its language.
* symtab.c (find_main_filename): Remove.
* symtab.h (find_main_filename): Remove.
* gdb.base/maint.exp: Allow zero symtabs to be expanded.
This is another patch in my ongoing series to "split" objfile to share
more read-only data across inferiors. See
http://sourceware.org/gdb/wiki/ObjfileSplitting
When symbols are finally shared, there will be no back-link from the
symbol to its containing objfile, because there may be more than one
such objfile. So, all such back-links must be removed.
One hidden back-link is the msymbol_objfile function. Since
(eventually) a symbol may appear in more than one objfile, trying to
look up the objfile given just a symbol cannot work.
This patch removes msymbol_objfile in favor of using a bound minimal
symbol. It introduces a new function to make this conversion simpler
in some spots.
The bonus of this patch is that using msymbol_objfile is slower than
simply looking up the owning objfile in the first place.
