Set list_in_scope later in DWARF reader

Browse Source 
Currently the DWARF reader sets the list_in_scope member of the CU
when first starting to process symbols.  Future changes will make this
assert -- code will not be able to refer to these lists until after
start_symtab has been called.  This patch prepares for the problem by
arranging to initialize list_in_scope in dwarf2_start_symtab.
