middle-end/104467 - fix vector extract simplification

This fixes a bogus vector type used for a CTOR build as part of
vector extract simplification.  The code failed to consider a
CTOR of vector elements.

PR middle-end/104467
* match.pd (vector extract simplification): Multiply the
number of CTOR elements with the number of element elements.

* gcc.dg/torture/pr104467.c: New testcase.
