        * hsa.h (hsa_function_representation): Remove prologue member.
        * hsa-dump.c (dump_hsa_cfun): Iterator over all BBs.
        * hsa-gen.c (hsa_function_representation): Don't init prologue,
        start with zero bbs.
        (hsa_function_representation::get_shadow_reg): Use entry block,
        not prologue member.
        (hsa_init_data_for_cfun): Create hsa_bb for entry/exit blocks.
        (hsa_deinit_data_for_cfun): Deallocate also for entry/exit blocks.
        (gen_hsa_insns_for_kernel_call): Don't use UINT64_MAX, but
        the built-in max value of the type.
        (gen_function_def_parameters): Don't use prologue member, but
        the hsa bb for entry bb.
        (wrap_all_hsa_calls): Iterate over all BBs.
        * hsa-regalloc.c (naive_process_phi): Revert 2015-08-19 change.
        (naive_outof_ssa): Iterate over all BBs.
