- Subject: [Ada] Do not generate special PARM_DECL in LTO mode
We generate a special PARM_DECL for Out parameters passed by copy at -O0, but
it doesn't play nice with LTO so this patch removes it when LTO is enabled.
Tested on x86_64-suse-linux, applied on the mainline and 4.7 branch.

* gcc-interface/decl.c (gnat_to_gnu_entity) <E_Out_Parameter>: Do not
generate the special PARM_DECL for an Out parameter in LTO mode.
