    x86: Fold arch_names_table into processor_alias_table

    In i386-builtins.c, arch_names_table is used to to map architecture name
    string to internal model.  A switch statement is used to map internal
    processor name to architecture name string and internal priority.

    model and priority are added to processor_alias_table so that a single
    entry contains architecture name string, internal processor name,
    internal model and internal priority.  6 entries are appended for
    i386-builtins.c, which have special architecture name strings: amd,
    amdfam10h, amdfam15h, amdfam17h, shanghai and istanbul, and pta_size is
    adjusted to exclude them.  Entries which are not used by i386-builtins.c
    have internal model 0.  P_PROC_DYNAMIC is added to internal priority to
    make entries with dynamic architecture name string or priority.

            PR target/95842

            processor model and priority to each entry.
