The attached change fixes a reload failure encountered testing another
change. It occurred for a constant that didn't match the "J" constraint.
The change makes the HImode pattern the same as the corresponding SImode
pattern.
Tested on hppa-unknown-linux-gn, hppa2.0w-hp-hpux11.11 and
hppa64-hp-hpux11.11. Committed to 4.6, 4.7 and trunk.
