In simplify-rtx.c(simplify_binary_operation), an assertion of "VECTOR_MODE_P (GET_MODE (trueop0))" causes an unnecessary ICE. This patch relaxes the assertion into a "if (non-vector-mode) then return 0". Given the returned zero, the caller (combiner) realizes the given RTX is illegal, and it eventually figures out something else that will work.
This testcase currently provokes an ICE with the mainline GCC for x86.
Also available in Bugzilla:

May I commit this testcase to mainline under gcc/config/testsuite/gcc.dg ?
