Hi,
I'd like to commit the following patch. It only affects ports where
CGEN_INT_INSN_P is 0. Currently that's only the fr30 port. Testing
showed no regressions.

* cgen-ibld.in (insert_1): Switched bfd_get_bits and bfd_set_bits
calls to cgen_get_insn_value and cgen_put_insn_value calls.
(extract_1): Switched bfd_get_bits call to cgen_get_insn_value call.
