re PR middle-end/91623 (-msse4.1 -O3 segfault in /usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/include/smmintrin.h:270:10)

PR middle-end/91623
* optabs.c (expand_vec_cond_expr): If op0 is a VECTOR_CST and only
EQ_EXPR/NE_EXPR is supported, verify that op0 only contains
zeros or negative elements and use NE_EXPR instead of LT_EXPR against
zero vector.

* gcc.target/i386/pr91623.c: New test.
