Correct handling of constant fields.
* gen.c (insn_field_cmp): Tweak comment about neither field
being an insn_field_string with a cond_eq-to-value condition.
(insns_bit_useless) <case insn_field_string, case
decode_find_mixed>: Handle cond_eq-to-value fields as
insn_field_int.
* gen-idecode.c (print_idecode_validate): Handle
insn_field_string cond-equal-to-value fields as insn_field_int.
* gen-icache.c (print_icache_body): Add comment why constant
string fields are handled.
