There is no significant difference in the backend between 4.1, 4.2
and the trunk in the handling of QImode and HImode in the floating
registers. What's changed is reload.

The simplest fix is probably not to allow QImode and HImode values
in the floating point registers as there's no instructions that operate
on them.
