expand: Fix up LTO ICE with COMPOUND_LITERAL_EXPR [PR99849]
The gimplifier optimizes away COMPOUND_LITERAL_EXPRs, but they can remain
in the form of ADDR_EXPR of COMPOUND_LITERAL_EXPRs in static initializers.
By the TREE_STATIC check I meant to check that the underlying decl of
the compound literal is a global rather than automatic variable which
obviously can't be referenced in static initializers, but unfortunately
with LTO it might end up in another partition and thus be DECL_EXTERNAL
instead.

PR lto/99849
* expr.c (expand_expr_addr_expr_1): Test is_global_var rather than
just TREE_STATIC on COMPOUND_LITERAL_EXPR_DECLs.
* gcc.dg/lto/pr99849_0.c: New test.
