simplify-rtx: Fix VOIDmode operand handling in simplify_subreg [PR108805]
simplify_subreg can return VOIDmode const_int operand and will
cause ICE in simplify_gen_subreg when this operand is passed to it.
The patch uses int_outermode instead of GET_MODE of temporary as the
innermode argument of simplify_gen_subreg.

* simplify-rtx.cc (simplify_context::simplify_subreg): Use
int_outermode instead of GET_MODE (tem) to prevent
VOIDmode from entering simplify_gen_subreg.

* gcc.dg/pr108805.c: New test.
