Kill init_sal

Instead, make symtab_and_line initialize its members itself.  Many
symtab_and_line declarations are moved to where the object is
initialized at the same time both for clarity and to avoid double
initialization.  A few functions, like e.g., find_frame_sal are
adjusted to return the sal using normal function return instead of an
output parameter likewise to avoid having to default-construct a sal
and then immediately have the object overwritten.

gdb/ChangeLog:
2017-09-04  Pedro Alves  <palves@redhat.com>

	* ada-lang.c (is_known_support_routine): Move sal declaration to
