debug/107058 - gracefully handle unexpected DIE contexts
While the bug is persisting that LTO streaming picks up a CONST_DECL
from an attribute argument on a VAR_DECL which with -fdebug-type-section
refers to a DIE in a type unit we can handle this gracefully, at least
with -fno-checking. Do so. The C++ frontend nevetheless should resolve
the CONST_DECL attribute argument to a constant.
PR debug/107058
* dwarf2out.cc (dwarf2out_die_ref_for_decl): Gracefully
handle unexpected but bogus DIE contexts when not checking
enabled.
* c-c++-common/pr107058.c: New testcase.
