* igen.c (insn_table_load_insns): Add support for model-static for
internal functions that should not be inlined.
(lf_print_c_semantic): Remove model_cleanup.
(gen_model_{c,h}): Ditto.
* ppc-instructions: Redo model specific support once again. Add
floating point support to the model specific information. Flesh
out all of the floating mutiply add/subtract instructions. Add
better tracing support to the model specific information.
