vect: Don't apply masks to operations on invariants [PR108979]
The loop body in the testcase contains an operation on invariants.
SLP detects this and can hoist/schedule the operation outside of
the loop. However, after the fix for PR96373, we would try to
apply a loop mask to this operation, even though the mask is
defined in the loop.
The patch does what Richi suggested in the PR: suppress the
masking for externs and constants.
