This fixes ICE in combine caused by an invalid constant for SImode.
We should have been using gen_int_mode.  A similar fix was applied
on arm a few months ago.

This is a regression caused by my rewrite of casesi a few years ago.

Other uses of GEN_INT in pa.md need to be reviewed.  I think there
are a few more uses that need to be changed.

Tested on hppa64-hp-hpux11.11.  Committed to 4.5, 4.6 and trunk.
