Introduce objfile::reset_psymtabs
This introduces a new method, objfile::reset_psymtabs, and changes
reread_symbols to use it. This method simply destroys the existing
partial symbols and recreates the psymtab_storage object.
This patch fixes a latent bug -- namely, that reread_symbols should
clear objfile::psymbol_map, but does not. I can submit that
separately if you'd prefer.
