PR bootstrap/80486 - spurious -Walloc-size-larger-than and -Wstringop-overflow in dominance.c during profiledbootstrap
gcc/ChangeLog:
PR bootstrap/80486
* dominance.c (dom_info::m_n_basic_blocks): Change type to unsigned.
(new_zero_array): Adjust signature.
(dom_info::dom_init): Used unsigned rather that size_t.
(dom_info::dom_info): Same.
