Hi,
this patch fixes ICE in free_lang_data compiling lto8.adb.
The fix is bit symptomatic becuase type_with_linkage_p should return
false for Ada types. Perhaps adding explicit flag to DECL_NAME would
make sense but it can wait for next stage1.
The fix works because at this stage of free_lang_data all mangled names
must be computed and thus it is cheper to test presence of
DECL_ASSEMBLER_NAME anyway.
Bootstrapped/regtested x86_64-linux, comitted.

* tree.c (fld_simplified_type_name): Use DECL_ASSEMBLER_NAME_SET_P
instead of type_with_linkage.
