Fix IPA modref ubsan.
modref_tree<tree_node*>::merge(modref_tree<tree_node*>*, vec<modref_parm_map, va_heap, vl_ptr>*, modref_parm_map*, bool)
is called with modref_parm_map chain_map;
The variable has uninitialized m.parm_offset_known and it is accessed
here:
gcc/ipa-modref-tree.h:572 a.parm_offset_known &= m.parm_offset_known;
PR ipa/103230
gcc/ChangeLog:
* ipa-modref-tree.h (struct modref_parm_map): Add default
constructor.
* ipa-modref.c (ipa_merge_modref_summary_after_inlining): Use it.
