    analyzer: fix ICE on globals with unknown size [PR93388]

    This patch fixes an ICE seen when attempting to build various existing
    tests in our testsuite with -fanalyzer, including
    gcc.c-torture/compile/980816-1.c.

    gcc/analyzer/ChangeLog:
            PR analyzer/93388
            * region-model.cc (region_model::get_initial_value_for_global):
            Fall back to returning an initial_svalue if
            decl_region::get_svalue_for_initializer fails.
            * region.cc (decl_region::get_svalue_for_initializer): Don't
            attempt to create a compound_svalue if the region has an unknown
            size.

    gcc/testsuite/ChangeLog:
            PR analyzer/93388
            * gcc.dg/analyzer/data-model-21.c: New test.
