re PR rtl-optimization/89445 (_mm512_maskz_loadu_pd "forgets" to use the mask)
PR rtl-optimization/89445
* simplify-rtx.c (simplify_ternary_operation): Don't use
simplify_merge_mask on operands that may trap.
* rtlanal.c (may_trap_p_1): Use FLOAT_MODE_P instead of
SCALAR_FLOAT_MODE_P checks. For integral division by zero, if
second operand is CONST_VECTOR, check if any element could be zero.
Don't expect traps for VEC_{MERGE,SELECT,CONCAT,DUPLICATE} unless
their operands can trap.
* gcc.target/i386/avx512f-pr89445.c: New test.
