        PR hsa/70391
        * hsa-gen.c (hsa_function_representation::update_dominance): New
        function.
        (convert_addr_to_flat_segment): Likewise.
        (gen_hsa_memory_set): New alignment argument.
        (gen_hsa_ctor_assignment): Likewise.
        (gen_hsa_insns_for_single_assignment): Provide alignment
        to gen_hsa_ctor_assignment.
        (gen_hsa_insns_for_direct_call): Add new argument.
        (expand_lhs_of_string_op): New function.
        (expand_string_operation_builtin): Likewise.
        (expand_memory_copy): New function.
        (expand_memory_set): New function.
        (gen_hsa_insns_for_call): Use HOST_WIDE_INT.
        (convert_switch_statements): Change signature.
        (generate_hsa): Use a return value of the function.
        (pass_gen_hsail::execute): Do not call
        convert_switch_statements here.
        * hsa-regalloc.c (hsa_regalloc): Call update_dominance.
        * hsa.h (hsa_function_representation::m_modified_cfg):
        New flag.
        (hsa_function_representation::update_dominance): New function.
