This enhances location description generation so that the generated
opcodes for integer literals are as space-efficient when HOST_WIDE_INT
is 64-bits large than when it's 32-bits large. In particular, this
reduces the size of the opcodes generated to produce big unsigned
literals using small literal integers instead.

In Ada, it is possible to have nested subprograms in the following
configuration:
procedure Parent is
type T;
[...]
procedure Child (Value : T) is
begin
[...]
end Child;
begin
[...]
end Parent;
As we currently generate debugging information for Child first before
Parent, the debug info for T appears in global scope since the DIE for
Parent does not exist yet.
This patch makes sure that when we generate early debug info for a
nested function, we trigger generation for the parent function first.
