Hi,
the test fails at -O2 because of the assertion recently added to gen_reg_rtx
that crtl->emit.regno_pointer_align_length is non-zero. Now the function
expand_vec_perm_interleave_2 can be invoked at the GIMPLE level in "testing"
mode and crtl->emit is not initialized by that time.
Tested on ia64-linux-gnu, OK for mainline and 4.9 branch?

* config/ia64/ia64.c (expand_vec_perm_interleave_2): Use gen_raw_REG
to create a register in testing mode.
