[Bug rtl-optimization/29323] set_nothrow_function_flags does invalid analysis on weak functions

While except.c:set_nothrow_function_flags analyzes rtl, the DECL_NOTHROW flag
it computes is a tree bit.  via calls.c:flags_from_decl_or_type ->
calls.c:call_expr_flags -> tree-eh.c:tree_could_throw_p makes this information
is made available to the tree optimizers.
