I'm not sure why you changed these. In general we try to keep lines
under 80 columns in the source. Things like insn reservations are in a
grey area as the lists sometimes get very long. In general I'd leave
this stuff alone if it doesn't have a function change.

Note that some of the stuff pointed out on patch #1 applies here to,
like rdfrm not being a vector load/store. So as you clean up patch #1,
make sure to mirror the cleanups in patch #2 of the series.
