[IA-64] Fix ICE on gcc.dg/vect/vect-cond-11.c

[Eric Botcazou]

I happened to note that there is an ICE in the C testsuite on IA-64 and that 
it is trivial to fix, so here is the result.

Tested on ia64-suse-linux, applied on the mainline and 5 branch as obvious.

        * config/ia64/ia64.c (ia64_expand_vecint_compare): Use gen_int_mode.
