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.

equivalent 32-bit constant (modulo 2**32) when that yields

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.
gcc/
* dwarf2out.c (dwarf2out_early_global_decl): For nested
functions, call dwarf2out_decl on the parent function first.
