gdb: move compunit_filetabs to compunit_symtab::filetabs

Browse source 
Make compunit_filetabs, used to iterate a compunit_symtab's filetabs, a
method of compunit_symtab.  The name filetabs conflicts with the current
name of the field.  Rename the field to m_filetabs, since at this point
nothing outside of compunit_symtab uses it, so we should treat it as
private (even though it's not actually private).  Rename the
last_filetab field to m_last_filetab as well (it's only used on
compunit_symtab::add_filetab).

Adjust the COMPUNIT_FILETABS macro to keep its current behavior of
returning the first filetab.
