i386: Handle unsupported modes from ix86_widen_mult_cost [PR109807]
Revert my previous change that faked handling of V4HI and V2SImodes
in ix86_widen_mult_cost and rather return arbitrary high value
for unsupported modes. This should prevent cost estimator from
selecting non-existent vector widen multiply operation.
