PR rtl-optimization/87065
* combine.c (simplify_if_then_else): Formatting fix.
(if_then_else_cond): Guard MULT optimization with SCALAR_INT_MODE_P
check.
(known_cond): Don't return const_true_rtx for vector modes.  Use
CONST0_RTX instead of const0_rtx.  Formatting fixes.

* gcc.target/i386/pr87065.c: New test.
