analyzer: fix ICE when DECL_INITIAL is error_mark_node [PR98580]
lto-streamer-out.c's get_symbol_initial_value can return error_mark_node
rather than DECL_INITIAL as an optimization to avoid extra sections for
simple scalar values.
Add a check to the analyzer to handle such cases gracefully.
gcc/analyzer/ChangeLog:
PR analyzer/98580
* region.cc (decl_region::get_svalue_for_initializer): Gracefully
handle when LTO writes out DECL_INITIAL as error_mark_node.
gcc/testsuite/ChangeLog:
PR analyzer/98580
* gcc.dg/analyzer/pr98580-a.c: New test.
* gcc.dg/analyzer/pr98580-b.c: New test.
