debug/78112: remove recent duplicates for DW_TAG_subprogram attributes
Disable unnecessary calls to dwarf2out_decl for the parents of nested
functions. This fixes a libstdc++ build regression on
x86_64-apple-darwin, as these calls used to add duplicate attributes
(for instance DW_AT_inline and DW_AT_object_pointer) to the
corresponding DW_TAG_subprogram DIE.
Bootstrapped and regtested on x86_64-linux.

* dwarf2out.c (dwarf2out_early_global_decl): Call dwarf2out_decl
on the context only when it has no DIE yet.
