Do not allocate psymtabs via psymtab_storage 

Currently, partial symbol tables are allocated by a method in
psymtab_storage.  However, eventually we want to subclass partial
symtabs in the symbol readers, so the calls to "new" will have to
happen there.  This patch is a first step, moving the allocation from
psymtab_storage and into allocate_psymtab.
