PR symtab/17559

Basically the problem is that "symtab" is ambiguous.
Is it the primary symtab (where we canonically think of
blockvectors as being stored) or is it for a specific file
(where each file's line table is stored) ?

gdb_disassembly wants the symtab that contains the line table
but is instead getting the primary symtab.
